I bought my Tab from craigslist, brand new, never opened. I didn't want T-Mobile service because I can just tether my 3G through my EVO. Can anyone tell me if I need T-Mobile in order to use GPS? Every time I turn on my GPS and Google Navigation, it's always saying "Searching for GPS."
No, you don't need T-Mobile service to use GPS. It takes long time to lock to satellites if you don't have adequate level of GPS signal (cloud, inside building...)
This happened to me....
Instead of going into the Blue arrow, I started IN Google Maps, got directions for somewhere and then through the menu selected Navigate. It was weird, I almost returned my tab, no help from CSR. This seemed to "jumpstart" the process and now it works everytime.
no working
will mine is not working it keeps on checking navigation availability display and iam out side and not near any towers and the sky is clear

Correct me if I am wrong but the Tab does not have full sat GPS only A-GPS which triangulates using communication towers. Not only is this less accurate but if your out of phone signal range then your GPS does not work.
This is why I can't understand why there are car docks for the Tab and no mention of the restrictions. I for one spend time in National Parks and remote areas so the Tab as a GPS device is next to useless to me.

Like I said I hope I am wrong but you don't need a sim to get a signal.
I have seen GPS sat info as well but presumed it was being simulated via net.
When I first researched the tab I found many sites claiming the tab had no dedicated GPS chip but instead used 3g chips agps capabilities.
Unfortunately it seems there is no system info or sensor info apparently that will give you this info. At least not one I have found.

The Samsung Galaxy Tab has a Broadcom BCM4751 standalone GPS receiver which has A-GPS (assisted GPS) capability so when a 3G connection is available it will download GPS assistance data over the high-speed cellular network decreasing the time for GPS location determination. The Broadcom BCM4751 is a very small single chip GPS receiver with a massively parallel, hardware correlator architecture to speed signal searches and very low average power consumption to suit mobile devices. It includes software optimized for cellular integration and personal navigation performance and includes sophisticated algorithms to mitigate multi-path errors.
It does have aGPS, but its to BOOST the performance of using the receiver chip alone. Helps keep it from dropping out easily.

Thanks very much for that.
I know a-gps in many devices work along aside a dedicated chip using tower triangulation to speed up real GPS acquisition but there also many devices that claim to be GPS with no dedicated chip and are a-gps only.
It seems at the time of my research the pre-release/preview versions of the tab did not have a dedicated GPS chip. Some previews/reviews were based on this version. Apparently after a few user discussions at a later date Samsung decided to add the Broadcom chip for the official release version. Problem is these initial reviews still exist.
Anyway that is great news to me
Hope the op managed to sort his issue out.

Have you tried any GPS Apps from the market? It may not be getting a fix but is it seeing any satellites at all?
"GPS test" is free and will show you sat info.

What Tab do you have Sprint? DId you buy it used? Maybe the person previously screwed up the firmware and used the *ALMOST STOCK Rom from these forums to recover most of the stock firmware. This screws with the modem.bin file and renders the GPS bricked.
Nothing you can do about it now but wait till someone figures out how to extract the modem.bin file properly, or a big update gets released.
Hi, I bought my Tab new from the open market not from any carier but I do have a data plan though from Etisalat a local carier over here in Dubai, could it be the carier is blocking the service, but then that does not make any since because I also not getting the sats on the wifi (i do have powerful wifi connection I could stand out side of my house and still have connection to my wifi)

So it's not hardware or firmware and you can get a fix so it must be google nav. it's self.
I can only think of the simple suggestion that you try uninstalling google maps using the app manager. Then try downloading and installing it from the market place.
Google navigation
hi guys
just a question, is there a deference between google maps and google navigation?
i am asking because i got two deferent widgets on my tab and thats how it was since the beginning i searched for google navigation in the market but could not find it but i got the latest google maps ver 5.0.0

The gps of the tab does suck.
I use it daily for running and cycling.
I go outside, remove the tab from the leathercase, start trackerbooster, hold it in the air, and still have to wait several minutes for a gps-lock.
In the car its almost impossible to use gps without stopping and going outside first.
Thats because it sucks.
I use the GPS for various things including turn-by-turn. Sometimes it refuses to get a proper lock though. Usually in that case, powercycling the GPS chip results in a lock within about 15-30 seconds.

I think they are two seperate programs as such with nav using api's from google maps but they both are installed under Google Maps app. Both are installed via the google maps market app.
Saying that....does google maps get a fix?

All my phone/PDA devices with GPS act this way including the GPS on my Touch HD2 and the older Touch HD.
I would only expect GPS dedicated devices that have better hardware or a GPS device that allows an antenna to be connected to perform much better.

My Nexus One will get a GPS lock in a matter of seconds, if I hold my SGT right beside it, it can take close to a full minute before it gets a lock.
Even if they can both "see" the same number of satellites (via GPS Test), the SGT generally won't get a lock until it can see at least 7 of them, whereas the N1 seems happy with 4 or 5.
The GPS on the SGT is virtually useless, it's too slow to lock and too innaccurate when it does, which is a real pity as the Navigon GPS app that it comes with is much nicer than the Google Navigation app as the maps are stored locally and the directions are more precise.
Is this a hardware issue or a software issue? Surely the hardware in the N1 isn't any better?

So Google is currently offering a beta version of the GPS Emulation software in the latest Google maps. My problem is that I can't get it to work with my Sprint Touch (Vogue), I keep getting a "Your location is currently unavailable" message. A co-worker of mine is able to get the My Location feature to work on his Blackberry. I was wondering if sprint is blocking this part of the software. Any insight into this issue would be greatly appreciated. Thanks in advance.
Edit: Yeah sorry my location is Chicago, IL and my carrier is Sprint. Apparently it works on the regular touch so maybe a different ROM would fix it. According to Google the reason My location isn't working is because "The device is not reporting a cell". Now I haven't got a clue what that means, so if someone more knowledgeable has any idea any help would be greatly appreciated.

Hasn't worked for me either in the Baltimore <-> DC area. I'm assuming Sprint is blocking it.
If you do get it working report your general area and cell provider.
The GPS feature of the Sprint Touch has not been activated yet, offcially.
Unless I am misunderstanding your questions... It won't work until GPS is turned on...

This services uses Cell Tower Triangulation when GPS is not available...SO it should still work
As well sprint does list the Touch as one of the phones that works with their Family Locator software. So...
I was wrong...

Sorry, I was wrong about the GPS comment...
I'm on Bell in Canada, the GPS locating didn't work for me but I did get an automated call from Bell the other day welcoming me to their service, the message also mentioned that my "phone has a global positioning chip that will help locate you in a case of emergency"
So we need to figure out how to unlock GPS. I heard Sprint will be providing an update that unlocks it sometime soon, but that doesn't help me
I have a Htc Touch with Telus, and because GPS is disable for now, I was able to configure a External gps receiver with Google Maps mobile. Works very good.
Google Maps
The locator in Google maps doesnt have anything to do with GPS. I have sprint with the touch in Utah and mine doesnt work either.
The google maps locator is based on cellphone tower triangulation and it seems to be not compatible with sprint at this time. I 'think' microsoft is working on this with sprint for live search too ... someone in livesearch told me the other day "I can't tell you what we're working on but we've got more new things coming (for livesearch)" when I mentioned it.
..cont
It's a nifty idea and free but it's not all that accurate... like a few blocks to a mile or more.
I don't know about you but when I'm in my car I can usually tell you where I am within a mile or so without the help of a satellite or other electronic devices.
If the live search rumor is true that is great, but my interest in this is not to know where I am, but to know what is around me.
I don't this this technology will work with Sprint or Verizon because of the way CDMA works. Maybe in the future but not now.
Here's the article that said it was coming on Live Search/Sprint
http://www.engadgetmobile.com/2007/09/18/sprint-microsoft-roll-out-location-based-live-search/
Sprint, Microsoft roll out location-based Live Search
Posted Sep 18th 2007 12:02PM by Donald Melanson
Filed under: Software, Sprint
It looks like Sprint users now have a few more search options at their disposal, with the carrier and Microsoft announcing today that Live Search will now automatically take the users' location into consideration. Apparently, the service makes use of cell-tower triangulation, and not GPS, to determine the users location, making it somewhat less accurate but far more widely available. What's more, the pair also announced a new voice search feature that'll work with five of Sprint's high end phones, including the Samsung a900 and a920, the Motorola Razr, the Sanyo 840 and the LG 550. As you can probably guess, it will let you speak search terms instead of typing them in, with it also giving you the option to press a button to call the business you're searching for. While Sprint is getting all Microsoft's attention at the moment, the company is quick to point out that the service is not exclusive, and "could become available via other operators in the future."

I'm on Bell Mobility in Ottawa, Canada (Village of Carp) and "Your current location is temporarily unavailable" shows up for me too. I have the Vogue and blazing 1 Mbps speed. I'm opening up Google Maps every time I go out and hit 0 trying to get the towers more input. What is the word on Bell and Google Maps, am I doing this for nothing? Greater Ottawa has a population of 1 million, is Canada's capital and, therefore, should be a large dot! Mind you, best we stay hidden from nukes I guess....

I am in the GHBOA - Greater Hamilton, Burlington, Oakville Area (anyone who lives here will think that’s funny) and also on Bell Mobility and I am getting the same “Your current location is temporarily unavailable” message.
I double-checked to make sure that my location service was turned on. My understanding from what I have read is that Google Maps will:
A) Use true GPS if present and show a blue dot to represent approximate location.
B) Fall back to tower triangulation if GPS is not available and show a blue dot with a light blue “halo” around it to represent approximate location.
On top of that I think we have also established in another tread on this board that the Vogue does indeed have a true GPS receiver inside but we are waiting in a firmware upgrade to enable it. In the meantime however the approximate location service using tower triangulation should work.
Perhaps GSM and CDMA networks report tower triangulation information differently and perhaps Google Maps only knows how to use the GSM info??? I have no idea if that makes sense but we CDMA folks do seem to get the short end of the stick a lot
I have a crazy idea that I want to “air” here and see what others think. Could it be that the Google Maps “My Location” feature doesn’t work on the Vogue because the Vogue has a real GPS receiver that is currently disabled?
I am thinking this because I did the following:
Start > Settings > System > External GPS > Access
There I disabled the “Manage GPS automatically”. This feature apparently gives Windows control of the GPS receiver and Windows marshals which programs can access it.
I then reset Google Maps and tried “Menu > Use GPS”. This resulted in “Initializing GPS” for a few minutes after which I got a message saying my GPS receiver wasn’t responding.
However I then went back into Start > Settings > System > External GPS > Access and re-enabled the “Manage GPS automatically” feature. I then went back into Google Maps (after resetting it again) and tried “Menu > Use GPS”. This time it resulted in a “Seeking GPS satellites (0)” message that never seemed to stop and never reported an error message.
So, my thinking is that perhaps Google Maps knows there is a physical GPS receiver in the Vogue and is trying to talk to it indefinitely and as a result is not falling back to tower-triangulation mode. Because the GPS is present but not enabled in the firmware Google Maps knows it is there but isn’t getting the appropriate response that would cause it to give up on GPS and switch to “tower” mode.
Just a thought... Does this sound reasonable to anyone?
That's exactly what I observed and thought as well, but people tell me I need more cell users to use GMaps for tower input. I'm beginning to think that's not the case, too many other reports of "unavailable" in highly populated areas. The Vogue just CAN'T do it on Bell CDMA. Has there been ANY positive reports with this box and CDMA? Nope...

I think we may just have to wait for that firmware upgrade that’s supposed to enable EVDO Rev A as well as the GPS.
At least this confirms that Google Maps behavior is modified by the GPS settings in Windows. It apparently “thinks” it is talking to a GPS receiver when you enable it on the Windows side. Assuming my theory is right maybe Google will come up with an update that lets the user specify to use tower-triangulation all the time regardless of the presence of a GPS or not.

Stand alone gps is about positioning by satellites.
Assisted gps means that (IF network operator supports it) your device will triangulate you by the cell of the operator in which you are.
No worries, Trinity has them both, gps in this device works flawless.

Thanks a lot for your rapid and perfect summary......
Actually, assisted GPS has nothing to do with operator support.

Actually, it has everything to do with operator support.
A-GPS is a network service. When using A-GPS, your mobile device receives useful satellite information from an assistance data server over the cellular network, which your operator might have or might not have.
A-GPS uses 3G and 2G cellular network connection and GPRS AND EGPRS packet data connection. You must also have an internet access point defined in your compatible mobile device.
So, bottom line, A-GPS is a network dependant feature that requires a data plan.

I reckon that I was a lil' bit terse in my previous post.
So, let's detail:
A-GPS depends on an assistance server, that is true. However, the server is completely independent and unrelated of and to the network operator. See below for more.
A-GPS requires packet data connectivity, that is true. However, it does not require any special properties on that connection. In other words, if you have internet connectivity on your device, that should suffice.
The operator can or cannot offer internet services, that is true. In that view, you might say that A-GPS is dependent of the network operator. However, the data plan is sufficient to have A-GPS working, there are no special restrictions on that.
Fact: I have a Nokia N95, which has A-GPS. My operator does not, in any way, advertise and or offer A-GPS service(s). However, simply having internet access on my device (and it being capable of A-GPS) is sufficient to get A-GPS working. The assistance server is, in this case, provided by Nokia, completely unrelated to my operator or its services. If you read Nokia's documents on getting A-GPS working, you'll find that it says exactly what I'm saying: A-GPS is not a network / operator service, the single requirement is to have internet connectivity on your device.
Hope I made things clearer this time.

...and the assisted server, which is not of your carrier's (so operator does not support A-GPS) must have it's cell tower data topography from somewhere. In this case operators might choose to or not to support this.
Let's see what others think about this.
Rest my case!
Assisted GPS is not uniquely dependent on cell tower topography. It can, for instance, help the GPS chip receive ephemerisis and or almanac data much quicker than it would do from the GPS satellites. Also, it can lessen the load on the CPU / GPS combo by offloading some intensive calculations to the assistance server. More so, the assistance server can have detailed knowledge of ionospheric conditions and GPS satellites' orbits so it can correlate fragmentary GPS data from the device's chip with that, in that it could quicker acquire a lock.
What I'm trying to say is that your only argument (so far) that A-GPS require cell tower topograhy (which, in some way, is dependent on the network operator) doesn't hold. Think about it this way: a device employing A-GPS (and keep in mind that A-GPS is not absolutely required for a lock) gets a fix, without using A-GPS. By the nature of the GSM network, it has access to its cell tower(s) ID(s). It then sends the cell tower ID and its position to the assistance server. In this way, the assisstance server can, in time, build a pretty reliable topography of the network.
So, no, it is not a network operator dependent service.

Sure, I never said I knew everything.
But I'm 99% sure that Nokia has no agreement with my operator regarding A-GPS (I have inside sources), still A-GPS is working in my setup and it's working pretty damn good.

I'm not saying you don't. Nokia's software may be working, but it might have information from other sources, not SMLC. I am referring to other sources as maybe Cell Broadcast/Cell Info (as in Busola Vodafone) messages or operator code readings.

Don't know what's in nokia's marketing department - but technically, Nokia's "A-GPS" is not real "A-GPS". It's a "Quick GPS" implementation (in HTC's terms). But that said, it has the obvious advantage of operator independence.
Nokia's A-GPS servers distribute satellite data, as with HTC's Quick GPS servers, so that the slow GPS would supposedly get a very quick hot fix.
I see.
Well, I'll dig a lil' bit more on this subject.

What is happening _I THINK_ is that Nokia is in a way reverse-engineering A-GPS the same way Google does with Google Maps.
When you are in GPS coverage and use navigation your phone is capturing both GPS coordinates and your GSM/UMTS cell information, creating a match between the two and saving it somewhere on a Nokia server.
Next time another user (or yourself) turns on the navigation program the cell-id information is transmitted immediately to the Nokia server which returns the necessary GPS information to avoid a cold start.
Basically the operator is by-passed but a mapping of cell-ids and geographical information is built anyway.
Technically this is not A-GPS but it serves the same purpose.

I don't own a Nokia, but I only heard people saying the fix is much faster using Nokia's "A-GPS". If it's really triangulate on CellID, then the fix would have great deal of error like few miles off the actual location. You may want to listen to what others said about using gmap with CellID only.
And even if it uses CellID, Nokia users have to contribute to such CellID data in the first place. So at least the early adopters would experience "slow" gps fixes - because no prior data was available. Apparently, they fixes were fast.
I would still say that this is a Quick GPS implementation using external satellite data from Nokia server.
Main issue!
So, Guys, the main issue: is A-GPS a network service or is it network independent?

What I said is that CellID is only used to avoid a cold start. I know that positioning based only on CellID would not be very accurate.
However mine was only a speculation. I have no idea of how Nokia has actually implemented this QuickGPS thing.
Sorry to drag this a bit off topic but the thread seems to have the attention of some experts!
I am running a trinity with wm6 al3x 3.1.2 and 1.50.08.11 radio.
When I use gps software will it automatically use assisted GPS to reduce TTF?
Apologies again for the hijack!
check htc's website for the update...
everything works great....google maps, tomtom....sats catch in seconds....awesome
lol....bell late as usual

I tried to download, link states 3.08.666.1
The downloaded file seems to be 1.19.666.1 (same as what is on my ROM)
What File did you get?
http://www.htc.com/us/FAQ_Detail.aspx?p_id=70&act=sd
go almost to the bottom and click the link for
Download HTC Touch (Bell) Update - Version 3.08.666.1
its under the gray box thats says
WARNING: During the upgrade process, do not attempt to make/receive calls, press any buttons on your device or disconnect the device from the USB cable as this will stop the update and your device will be rendered inoperable! Please be aware that your device may reset up to 4 times after the provisioning as your device updates.
This radio kicks ass. After I flashed it, I flashed NFSFan's ROM, works like a charm.
Does this work better than any of the other rom updates that we already have?
this rom works amazing and the gps locks in under 10 secs for me where it used to take like 8 mins
Bell wants to charges us for GPS
Not suprisingly, Bell wants to charges us for using the GPS functionnality of our "Plenty features that you better not use because we are wating to charge you all kinds of fees PDA phones"
My bill went higher than 400$ in 3 minutes by using the WModem, fortunately they credit me because it was the first time, and they told me to never use this pretty usefull feature again.
The new Bell rom Laucher has new icon, GPS NAV wich bring to this:

Is anyone of you was charged for using the GPS?
If I use AstroGPSLauncher, will Bell know that I am using GPS and charge me crazy money?
Thanks in advance
I'm using AstroGPSLauncher but I cant' get a valid GPS signal. It might be because Bell is charging everyone for the GPS use...
Will a custom ROM defeat this stupid, stupid fee?
it doesn't cost to use gps.....that new program is by bell which is supposed to be like 3d navigation such as tomtom....
for example....if u use google maps with gps...you shouldn't get charged...
I still can't get any signal. It waits for a valid signal forever.

These steps should work with googlemaps
1 - Go outside
2 - Start Google Maps
3 - Open menu -> Hit the use GPS
4 - Open menu again -> Hit My Location
It sould lock in les than 10 seconds
Aha, okay, I'll try that.
How about TomTom?
EDIT: I unfortunately do not have a data plan thus Google Maps will not work for me. But I did try your suggestion and when I hit 'My Location' it said My Location (Beta) is not supported on this handheld.

I did not tried TomTom yet.
Well I hooked my phone to my comp to get the data but it still won't grab any satellites..

I’m not trying to pick a fight here but it’s these kind of statements that make us look silly when we do have a legitimate beef with the wireless industry. Why do people get so upset when cellphone companies try to make money?!?!?!?!?

I am no fan of the wireless industry in North America (especially in Canada) but really… unlimited mobile browser isn’t the same as “unlimited high-speed internet everywhere on whatever device you can connect this thing to” for obvious reasons. It is precisely for these kinds of reasons the wireless industry has been so slow coming out with unlimited data plans on these devices. Why not buy a nice server from Dell and run a website out of my garage over my cellphone using my “unlimited” data plan?
All that being said, no you do not need to use the GPS app that Bell has bundled with the new ROM. You can use Google maps or any other GPS capable application. Personally I feel this is a very fair way for Bell to introduce this kind of a feature. Don’t try charging us to use something that is free (GPS) but bundle an app that adds value to the equation and if it’s really worth it people will use it and pay for it. What bugs us is when you try charging us for something without adding value to the equation. Ignore the Bell GPS app (unless you want to try it). You don’t need it for GPS functionality.

Are you on Bell??? Get the unlimited data feature for $7/month. This package is quite simply the best value in the wireless industry.
This ROM from Bell is top-notch. Easily the BEST one I have seen. A few weeks ago I got tired of waiting for Bell and broke down and flashed the Sprint ROM and then tried various custom ROM’s. None of the custom ROM’s came anywhere CLOSE to locking as fast or as accurately as this ROM from Bell. They might be late but they have the best ROM for GPS.
Talking about complaining….
How come we all complain about stuff like charges for data but no one seems to complain about the oldest ripoff in the books – “long distance”. Really!?!? I mean get real. Long distance used to cost more because involved operators plugging lines into a patch panel. Why does it still cost more? Especially when I am calling a place that I could drive to in 20 minutes. Really?!?!?! Long distance charges are a joke.
Fortunately my local calling radius is substantially larger on my cell phone then my home phone.
Oh, and talking about land-lines, what’s with dialing 1 before the area code? Has anyone ever stopped to consider what a backwards throwback that is? In the era of 10-digit dialing its more then a little annoying to hang up and dial again just because you weren’t sure if it was long distance or not.

So do we get charged for using the GPS?
And I also didn't know about the $7/month for unlimited data, I'll check into that.

No, you do not. You will get charged if you use the GPSNav application that Bell has included in this ROM.
To use the GPS feature for free download an app that is able to take advantage of it (for example Google Maps).

The $7/month data package from Bell is what makes the Touch such a hot device. Only avalible on the Touch.
Garmin and Asus have released several GarminFone with Garmin navigation software. I know it's not in 2.1.
Will there be garmin running on Nexus One(2.1 or 2.2)?
Thanks!
Why would you need that...
I agree, why would you need that if you can already download Google Maps from the market?
I have a Garmin Nuvi 265 T in my car and the software is almost identical to Google Maps Navigation.
lol. You can always tell when people have solid coverage all around them. For many of us no matter which carrier we are on we are often without coverage. That makes online mapping useless to us at those times, hence the need for having a solution that works without a data connection. There are also those who are running their phones on wifi without a data plan or those who are pay per kilobyte and would prefer not pull down the data required.
Garmin allows offline turn by turn right?
That's why someone would want garmin on their phones.
I dont believe that to be true.
If I have no satellite signal the Garmin barks right away.
You get a popup screen that says Poor Satellite Reception.
I've even seen it on a clear day without a cloud in the sky.

I believe the previous post was meaning "offline" as being not connected to the internet. The garmin units do not require an internet data connection but must be able to receive the GPS signal. When you are traveling outside your phone coverage area the data connection on your phone is worthless. Thus the need for a stand alone GPS unit.
Forgot to mention that Navigon is supposed to hit here shortly with their android navigation. I emailed them and they described the launch as "imminent". That one will reportedly come in two versions, a stand alone and a connected version.

Man, you are obviously in the dark about this thing, so why comment?
The guy is looking for an offline navigation app, one that has maps and routing abilities stored on the phone flash card. I need such a solution too and think it would be great to have a garmin app for android.
Unfortunately I am quite sure it will be non-profitable for garmin to release such, as it will be hacked in hours after the release.

Maybe I'll make it more clear...
People want to be able to navigate using GPS ONLY, not using EDGE/3G/HSDPA data.
There are already solutions for that, free and paid (cracked MotoNav adjusted for Nexus, CoPilot, Sygic, Waze etc), but naturally, people want better solutions, and some want Garmin - why not? Also, iGO is supposed to release the next Android version, which might be better than the one MotoNav is based on.
And yes, Nexus has a built-in GPS receiver. Too many don't understand the meaning of A-GPS, which is just a regular GPS, but the lock is acquired more quickly, using cellular triangulation to calculate approximate position and look for specific satellites available at that position, speeding the GPS lock time by a serious margin. Or using other algorithms for speeding up the GPS lock: http://en.wikipedia.org/wiki/Assisted_GPS

I'm going to spell it out as much as possible:
A Garmin system keeps all maps locally stored on the device, so the only signal needed is GPS (aka being outside). All route information is calculated on device, with no 3G/E needed.
The Google Maps system only stores what you have downloaded through 3G/E in its cache, so it needs a pretty constant 3G/E connection in order to download maps, navigation routes, etc, as well as the GPS to position. Not everywhere you go has a 3G/E connection, so Google Maps doesn't work everywhere.
Garmin only needs a GPS signal to navigate, Google Maps needs a GPS connection and a 3G/E connection.

good clarification !
now, about the google maps cache; how much "look ahead" does it cache, if any ? I haven't experimented with turning off connectivity (cellular) on the phone while using the navigation app yet, so I'm curious.
if it were easily possible to cache ohhh, just the route, on a 1000 meter resolution for a long trip, wouldn't that work fairly well ?
I'm sure someone here is a garmin/gmaps/copilot guru, and can answer that. Hope I haven't changed the subject too much.
I would like to see some posters in this thread use Google Maps abroad, you know when you actually need navigation, when they are roaming. Say hello to a pretty hefty phone bill if you used Google Maps for your navigation needs.
More offline map solutions are needed on Android and hopefully they will come soon.

totaly agree with you .... also in Bulgaria 1MB 3G/E traffic cost around 3EUR - so if i need to be navigated morning from home to my workplace it will cost me more then the fuel
Just to clarify, as I know, Google Navigation is just available in a few countries and it doesn't provide offline map and needs data connection to download map...
If your country doesn't have Google Navigation, or the expense of GPRS/EDGE/3G is expensive(for example, in xxx, it cost about 1.5$ for 1M), you will need Garmin or something else that provide offline map(doesn't need data connection), navigation.
Garmin is available in symbian and win mobile now. Hope Nexus One could have it soon...

The expense of adding my google account and downloading 2.1 update1 is 18.5$ when Nexus one was started for the first time. Just 19M data, can you imagine?

Android: When you're traveling where a cellular connection is fairly certain, Google Maps' own Navigation tool is a total GPS replacement. For those without data plans, or heading into the wilds, MapDroyd makes for a nice offline map backup.
When you start the app, you'll want to hit the Menu button and head right to "Manage Maps," where you can then drill down from continents to countries, to states and provinces and districts, and check off the maps you'd like to have available offline. Sizes will vary, but assuming you've got a decent microSD card installed, 34 MB for New York state, for example, is hardly a burden. The map data comes from OpenStreetMap, which has some fairly reliable highway and main thoroughfare information.
Gas stations and major restaurants will show up on your maps, as will other landmarks, depending on how well covered your area is by the open-source mapping crowd. You don't get directions or automatic searches of nearby spots, but the app can locate you by GPS. If it can't fix your GPS position, you will, unfortunately, have to manually zoom in from the world view to your own little corner of the world, where you're trying desperately to get back on the highway.
MapDroyd is a free download for Android phones only.

Nothing wrong with my gps. Have you upgraded to the latest firmware? Downloaded the A-GPS data (you can get this by using an app called GPS status)? Switch OFF wifi after you do, then leave it to get a full signal lock (takes up to 15minutes or so with a clear view of the sky).

Make sure you are outside with a clear view of sky when you test. It can take any GPS up to 10 minutes to acquire the ephemeris information (satellite position at a certain time) and lock up. You phone cheats this by using the cellular network to provide a general location of where your are and therefore where to look for certain satellites.
thanks so much for the info guys. I had a feeling it had something to do with no cell phone band helping out. thanks!
GPS works fine here, as other have said the closer you are to the sky/window the better.
yeah..give your TF a few minutes to lock up sat positions (if you've never done this)..
this applies to most pure gps devices..cellphones can use cellular network signal to quickly locate your position but the data isn't really from gps itself.

I wonder if it does the wifi cheat like maps for android phones, where it uses the known APs to determine location? I say that because when I first fired up my transformer yesterday, after connecting to wifi, I screwed around on maps and it found me inside my house in less than 30 seconds.

its the reverse for me! in the same room of house i often cannot get a fix on my Optimus 2x. i use GPS Staus app. but i often get fix within 30secs. as a test i have both machines running the app next to each other and the transformer always gets regular fixes.
..... hmm just realised as i type this that i have a phone called optimus and tablet called transformer, and they both run android!!!
I get fixes with no wifi (ie: only GPS) within 30 seconds.
Quite the opposite, mine is extremely accurate. After it gets a fix on maps that little google person is standing right in my front yard in the satellite view! Better than my Droid!
Mine is almost instantaneous. Just tried it at home based on this thread and had a read in probably 5 seconds.
I have not been able to obtain a GPS lock until today when I set my location to use wireless networks. To me this is really stupid because the GPS shouldn't have to use any location settings to obtain a lock in my mind. That is if the GPS chip in the TF is a true GPS chip it should not to rely on a wifi signal to obtain a lock. If the GPS is turned on then it should lock.
I tested sygic gps navigation 11 and signal lock and quality was better than my galaxy s was pretty accurate
Sent from my Transformer TF101 using XDA Premium App
Works fine for me, apart from one minor detail. When I switch from Google Maps to another app, even for a few seconds, then the tablet has to get a lock all over again. There appears to be no way to set the GPS to keep a lock while Google Maps isn't the active program.
That, for me, makes Google Maps near-useless in a moving vehicle. Hopefully other third-party apps won't have this issue.
Google Maps is prety much useless on the Transformer for GPS navigation as a data connection is need. I have heard of people caching a route before hand but ..... Copilot Live 7 is out for android so that is one option. However if the GPS relies on a wifi signal in order to obtain a lock then it is about useless too.

Gps works fine on mine....unlike my icons or Samsung...both returned
gps does use wifi to help gps locate, theres options to turn this off in settings, i went to pick up my dock today and couldn't get a gps lock while in the car with the transformer in my lap(gps status app showed 3 sats but none would lock) just lifting it up 12 inches closer to the windshield made 7 satellites pop up and instantly started getting locks
i think proximity to a window/line of sky is a big factor, and the transformer does have a true gps chip for those who seem to doubt it, also the navigation app keeps running in the background, its better to use that than google maps
No issues with gps here. The bastard finds me every time!

It doesn't rely on WiFi for a lock, it just uses it to allow a faster connection if you don't already have current ephemeris data downloaded. That's a limitation of all GPS receivers -- it takes a fair while to download the ephemeris data if you're out of date or have travelled a significant distance, and without it the device can't get a GPS fix.
You can think of the WiFi location system as analogous to a cellphone being able to use tower locations to help position itself while waiting for GPS ephemeris data.
