Garmin XT versus TomTom - Why is Garmin Slow to track location?

Hi all, I am currently testing Garmin XT and I noticed that there seems to be a bit of a lag in the GPS when you are driving around. I have TomTom currently which is flawless. Is there perhaps some setting I missed with Garmin or is this just the way it is???

I believe this has to do with the nature of the software drivers and the way they interact with the hardware of the phone. It is something that may be different from phone to phone.

Ahhh darn thats a shame I am running a mogul. What I like about Garmin is the fact that it has gas prices and traffic for free unlike TomTom. Anyone else experiencing the same issue?

seems to work fine for me, but I use it with the bluecharts maps and not any street maps.

Hmm well I just wanted to post a follow up not sure if this will help since I haven't tried on the streets yet. I went into the settings and by default Garmin had selected "Use GPD Intermediate Driver" which worked for me but again I saw a lag while driving around and frequent redrawing of where I was relative to the map.
So now I just went back to the settings and hit "disable" which then brought up a list "Use Bluetooth GPS" "Use GPD Intermediate Driver" and "Use Serial GPS". I then selected "Use Serial GPS" and selected COM4:COM4. I had to do this a couple of times the software would scan but not let me keep COM4 but after a few tries it found COM4. I don't know if this will make everything faster but I will keep everyone posted.

Well even after the changes I made seems garmin is just slow tracking and when you are driving that can really suck.

How slow is slow? I use Garmin now, and used to use Tomtom, and while it might seem that the arrow doesn't move quite as often, it still seems to be doing what it's supposed to. Is the screen not updating as often?

I have both on my Mogul -- I just updated the Garmin with the 2008 maps and tested it the other day on a 2 hour trip - it was dead on but I did use a blue tooth GPS antenna Holux 240Slim instead of the built in GPS -- I find the built in is dependent on a data connection which I will lose when I go out of area.
I noticed the Garmin was within a few feet of being dead on -- see an exit and there it was on the map - including the talking parts when I was told to exit right, etc
Mule

I've used both and I have found that XT is slightly slower in its frame rate then TOMTOM. However, I have been a long time GPS user and LOVE the fact that I can now load all of my topograhical and marine maps to my P4000! The detail and accuracy of XT makes TOMTOM maps look like something off Dora the explorer. TOMTOM didn't even have roads drawn in for my home town. It was just a peininsula into water. On XT you even see the ATV paths that follow the coast! With the topo maps you can pick a lake, hike to it and fish your brains out! XT takes it off road. Tomtom is of no use in that department. Its a hikers dream: music, communications, nav, camera and more in one small device. To bad the P4000 isn't waterproof. My Garmin Rino must be feeling left out....

you might want to check which driver you are using... I'm on 42020... I know I had problems with 42030 (resetting my clock and what not) and heard 42040 had issues to.. just a thought...

i believe all gps lag one second behind real time. tomtom is the only software that predict 1/2 and 1 second ahead.
btw, does anybody know how to limit garmin xt auto zoom? sometime it zoom out way too much.

you can turn off auto zoom but you can't "control" it.. the default is to zoom out to show next turn... I just keep it turned off...

I need a GPS system for my Titan, like this one.

This person has like the best ive seen so far does anyone know where i can get this GPS or something similar, please, i have the titan on the new 3.35 rom so any steps i need to follow, let me know, watch the linked video and youll see wat im saying http://www.youtube.com/watch?v=PDXXYuJSWM4

I don't recognize that exact piece of software, but basically any of the commercial ones will do the 3D view and turn by turn instructions like he had. I personally have used IGO and am currently trying TomTom6
I think I sway more towards IGO for a couple of reasons, but I'm trying to give TomTom a fair swing.

Are these GPS programs cracked or did you have to pay for them, and where would i find them?

some, like google maps, are free, others you have to pay for

There are a couple threads on XDA talking about GPS... I've tried most of them and personally, am happiest with Garmin's XT software. The only downside, is it uses a ton of memory with its latest release and will sometimes only run after a soft reset. I like its features for finding nearby gas stations with current prices, current traffic, weather, hotel rates, etc. If you are in Europe, it also has traffic safety cameras. All of these are included for no extra monthly fee (unlike TomTom).
On the other hand, I absolutely love TomTom for its quick page rendering. As you turn, the screen shows you turning smoothly... Garmin is quite jerky and not nearly as smooth as TomTom.
Both of them can plan a route for you quite nicely - both of them do end up giving me different directions from point a to point b, but neither seem to be horrible. Also - TomTom gives you directions in a couple of seconds. Garmin can take 30 seconds and sometimes up to a minute to calculate your route. Not a deal breaker.
I have heard some good things about iGo, but tried it several months ago and stopped using it for some reason - not sure why. I do remember it was nice because it included text to speech.
Google Maps and MS Live Search are both nice, but you need a continuous internet connection to render the maps. The above mentioned programs have the map stored on your storage card... only times it connects to the internet are for traffic updates, etc...
Good luck!

I myself am currently using Garmin Mobile XT. I've been using it for a while, and I love it. I'm on vacation now in North Carolina, and this thing hasn't skipped a beat for me at all. NONE. So I have no complaints.
I am rather curious to try out the newest distro of Tom Tom software when I can get it, and I wouldn't mind checking out Igo just to Give some feedback. I just haven't gotton around to it.

I have used IGuidance 4 and TomTom Nav 6 and Garmin XT
TomTom 6 is, I think, the best because it behaves itself most of the time. Garmin is a memory hog and IGuidance freaks me out because the different voices for the directions and the text to speech.
I like IGuidance's interface. I think v4 is very easy on the eye and the finger. But TT6 is smoother in 3D rendering, but due to lack of hardware acceleration in the Titan, none of them look particularly smooth compared to older HTC devices, or newer ones with proper graphics acceleration.
In terms of maps accuracy, TT6 seems to have the edge in North America and is far superior in Europe.
In Asia, I revert to MapKing as it is the only software with map coverage of any use. But then the MapKing interface is not up to TT6 or IGuidance level.
I like that IGuidance gives text to speech (i.e. "turn right in 100 meters at Oak Street" as opposed the "turn right in 100 meters") but as I mentioned the different voices freak me out a bit. I know there is a hack to make all the voices the same, but it degrades performance noticeably.
Overall TT6 is the best of the non data (google maps, live search) nav softwares for Europe, USA and Australia. Mapking for Asia.
Of the data services, Nav4All is pretty good for turn by turn directions, and Live Search is probably better than Google Maps for simple routing and mapping.

Touch HD same GPS lag as Touch Pro?

Just wondering if the Touch HD will get the same laging GPS receiver the Touch Pro and Diamond got? I sure hope not. Its the only thing that dissapoints me with my Touch Pro.

It's not an issue of hardware, but software. That's like asking if it will have the same laggy TouchFlo3D because of its processor... It's just the software. My Fuze didn't have any of the complaints of slow TF3D or GPS lag, but it had the same GPS receiver as the European Touch Pro.

I think the cause is the hardware, because some people tried with an external gps antenna, sirf3, and no lag at all. And changing software doesn't eliminate the lag. I use iGo and TT and the lag is always there...

Hopefully HTC will be able to fix the GPS Lag in the diamond and Pro with a rom update...they are supposed to be working on it. I just hope the Touch HD wont share the same lag problem and that HTC sees that it doesn't before release.

Isn't the difference between the built-in GPS and an external GPS antenna the method? The built-in GPS is (AGPS) and an GPS antenna uses "normal" GPS....

No, that's not it.
Assisted GPS is something extra for a normal GPS system, not a different system. A basic GPS system will have to download the satellites' position each time it cold-starts, and that will take time. An A-GPS system will have an additional way to download the current position of all GPS satellites, in order to speed up the process, by knowing the position of your phone in a GSM network or by downloading an updated file containing the satellites' current position, through a data network (wifi or 3g). That's why the "gps assistance" files you download through this kind of assistance application (in HTC's case, it's called "Quick GPS") are only valid for 2-3 days: in 2-3 days, they expire and the satellites' positions aren't valid anymore.
All GPS systems must have an antenna of some kind, either internal or external. Mostly all PDAs with integrated GPS have an internal antenna, which does the job in most conditions, but it's not perfect. I used an external antenna for car navigation, and in most situations I went from 4-5 detected satellites (with so-so signal) to 7-8 with full signal, only by having an antenna on the roof of my car. However, this shouldn't influence by all means the GPS lag, only the precision of GPS positioning on the map (coordinates).

That's not it either.
Quick GPS downloads a file prior to GPS initiation. When started the GPS works off-line.
A-GPS is a hybrid technology that auguments the GSM satellite signal with GSM signal on-line.
You can use Quick GPS without A-GPS, which is the case of most users today, for compatibility reasons.
As for the previous question regarding GPS lag, here are two points (depending on what you understand by GPS lag):
1. the GPS chipset has a built-in refresh rate, which should be something like 0.5 seconds. This is the same for all devices sharing the same chipset.
2. when saying that the GPS performance depends on software, it does not mean IGO or TomTom, it means the Radio drivers. Newer Radio versions come up from time to time and may improve GSM / GPS signal strength or battery life, and in the very best cases both.
Follow the ROM Development threads for more info.

Not to be a GPS-nazi but A-GPS doesn't necessarily imply the usage of a GSM network, but the usage of an assistance server. From Assisted GPS page on Wikipedia:
A typical A-GPS-enabled cell phone will use an internet connection to contact the assistance server. Alternatively, it may use standard non-assisted GPS, which is slower and less accurate, but does not lead to network charges for data traffic, which can be considerable.

So, it can be done either through GSM networks, or through a data connection; therefore, the Quick GPS app is simply another form of A-GPS.

That I don't think would be visible to the end user. According to the NMEA/SiRF specs, the min refresh rate would be 1 Hz (one time per second), but the average among devices seems to be around 5 times a second, once every 200 miliseconds (5 Hz refresh). The GPS chip should do that without a problem (according to the manufacturer's specs), therefore the problem must be somewhere after the GPS data is sent to the device; either in communication to the CPU, either in the navi software. My 2 cents. We'll see.

Review from SlashGear
HTC Touch HD's review by SlashGear talks about the GPS lag..
this is the part about GPS performance of the Device:
"The HTC Touch Diamond has been criticised for its GPS performance, which can lag behind actual position when moving at speed. Hopes were high for the Touch HD to avoid such a fate, but unfortunately that doesn’t appear to be the case. Whether from the processor (the same 528MHz Qualcomm MSM7201A as in the Diamond) or the GPS receiver itself, when driving the indicated position is always 50-80ft behind. This makes navigating via the on-screen directions incredibly difficult. At lower speeds, such as when walking, the Touch HD has no problems, just like the Diamond. We’re still attempting to get hold of some alternative GPS programs, such as TomTom or Garmin Mobile XT, and will update this review when we’ve had an opportunity to try them out."
has anyone else bought the Touch HD yet who can confirm this?
i just hope the GPS lag isn't as bad as the HTC Touch Diamond/Touch Pro as i'm going to order one pretty soon.

For the sake of millions of readers and potential touch HD buyers like me,can someone who already own a touch HD,please be kind enough,do an experiment about this gps lag issue and give an absolute answer to this issue.Gps lag is very noticeble when you are navigating at high speed(eg:80-100km/h) or when doing multiple rapid turns(eg:driving on back alleys).at low speed(slow drive or walking),no lag is apparent.Currently i'm using ipaq 612c where it has this lag issue and its most noticeble when using Garmin XT.When using mapking or tom tom it is not that bad..Really waiting for all your answers.
Thanks in advance for all your help

Ok, I have performed an experiment. Hopefully it will help you and "millions" of readers to decide if GPS lag is a problem or not on this device.
Test setup:
PDA 1: Mitac Mio A701, GPS chip: SIRF III, navigation software: IGO8
PDA 2: HTC Touch HD, GPS chip: Qualcomm, navigation software: IGO8
Experiment:
I start IGO8 on both devices and select the same destination. They both pick up GPS signal and the show starts..
Result:
PDA 1: depending on your speed, there is a GPS lag. This is between 0-2 seconds. In distance I would say about 20 to 50 meters. Again, all depending on your speed. When you stop (which unfortunatelly happens a lot in the netherlands due to high traffic ) the GPS gives the right position.
PDA 2: see PDA 1. There is practically no difference. Sometimes PDA 1 is more ahead, sometimes PDA 2 wins. The voice commands start virtually at the same time "take a turn left", "leave the highway" and so on. Maybe PDA 2 is a bit faster (less GPS lag) since I heard the voice like a 10th of a second earlier than on PDA 1.
Conclusion:
GPS lag is a problem that practically all "cheap" GPS devices have, specially in a moving vehicle. Since your GPS data is refreshed every second, you would be one second off every time. Moving at 100km/h, that means an offset of 27 meters. Moving at 150km/h that is about 41 meters (and yes, I know I should not drive that fast in the netherlands ). Add to that the GPS errors and you will get an impression on how hard it can be to predict where you will be in a second.
You could then say that the navigational software should take that into account and predict where it would be, but that also has a negative side. Have you noticed what happens when you do not follow the course laid ahead by the navigational software? it stays on course for a couple of seconds and then it notices you actually turned left or right, thus the direction should change.
The more aggresive the prediction is, the more you will have a problem when deviating. The less prediction, the more GPS lag you will have.
Is this a problem while driving? I have never considered it a problem. On the highway you do not decide to take a turn within 50 meters (I hope ). In the city, you should have way less problems with GPS lag...
Last, for all the "millions" of readers, please read these two articles:
Article 1, an abstract about navigational state estimator
Article 2, a forum discussing this very problem in the i-Blue receiver. Pay special attention to the answers given by JakeRich
I hope this helps you all out...

David,
I am so very pleased you had these two devices with the software mentioned.
It just so happens that I too have a Mio A701 with iGo and my next purchase will be the Touch HD.
Your test served as a good starting block for me to build upon.
I did wonder how well the Touch HD would fare against my A701.
Many thanks.
Beards

Thanks for your test. What about TMC info with iGo8 ?

The device finds the TMC receiver (using 8.0.x version, 8.3.x version does not find anything) but then it does not find a channel. This would need a TMC expert to work out...maybe you need to change something in the sys.txt file of IGO8

Something I would add is that until last week I was using a SirfStarIII equipped BT GPS receiver linked to my Hermes and running TTN 6.03, now I'm using the Touch HD internal GPS and TTN 7.45. I have found that the GPS signal appears to be significantly weaker on the Touch TD. However, it does have the capability to pick up more satellites it seems.
In my standard journey between home and work the BT GPS receiver never picked up more than 8 satellites but never picked up less than 4 and spent most time tracking 5-6. The Touch HD at times picks up 10, maybe even 11(!), satellites but often drops to 2 and spends most time tracking 3-5.

Impression
I'm using Tomtom 7,451 now on my HD.
I tried it with the internal GPs and even with an external bleutoth GPS receiver from Tomtom itself.
The so called lag is the same in both cases.It is caused by the slow refreshing rate ( almost 1 second ).That is not a major problem and is the same that I experienced already with the Polaris,Cruise and Diamond.
So when driving try to think at least 1 second ahead.
When you're not moving I got a pefect lock on my position with Tomtom but with Googlemaps i'm of by almost 150 meter to the East.
So that's software I think.

Google maps is already preinstalled, at least on my Touch HD it was (Netherlands)

last word on gpslag?
Hi to All,
Personally, i start realizing the limitation of forums in producing real information.
First of all, most "commercial" and consumer GPS update their position every second, as correctly pointed out in this forum. Said this, faster position updates are possible for professional devices, see
http://www.dsprelated.com/showmessage/22833/1.php
but we can probably forget about it for the time being.
so, don't be surprised if - driving at 100 km per hour alias 30 m/s - you will miss the exit by 30 meters. Be reassured: Felipe Massa will miss the box by 100m if he would drive by looking to the GPS - and your braking distance was anyway 60 m....aaaghh....i hope i will never meet any of you while making the test.
My firm and conclusive opinion after extensive evaluation with Igo and Tomtom and gwatch:
The GPS LAG on the touch HD is a metropolitan legend invented by i-members!
If you check on igo8, there is a small dot representing the actual position, and the arrow or the car is the position compute by software interpolation/filtering etc. Everybody can notice that the dot moves instantaneously. It is a matter of software to decide how to filter this data, and how "reactive" you want the position change to happen. On top of this, it is obvious that updating a VGA or WVGA screen will be heavier than updating a small screen, so there should be a lag which is dependent on the navigation software you use and on the load on your telephone.
However, there is definitely no lag on tomtom....the problem is: how to buy version 7?

Here is video comparison omnia vs hd
It seems to me there is little lag on hd.
Colud somebody translate it?

How is the GPS ?

What do you think about the GPS, which app would you recommand ?

People report back that TomTom version 7.915 is working fine......
Can recommend you TomTom

There's also a Copilot trial already in ROM, which is the other main option.

gps is excellent - better (more sats) than my rhodium and far far faster to lock than my kaiser. best yet in my opinion,

Does anyone know if IGO8 works with the mini? I am seriously considering this device since I at the point of being able to renew my contract.
Would love to know if anyone knows. Thanks!!!

Hi,
I have started a third party program which uses the gps.
When I turn off this program, the gps-icon in the tray doesn't go away.
I assume the gps is still running, but I can't find any settings to turn it off. Only thing that seem to work, is truning the phone off and on..
Anybody got an idea?

Hi stefanthege
I had this too with a little GPS app I use.
As far as I can see there isn't anything you can do to turn the GPS off, although it is supposed to shut down automatically if nothing is calling the GPS hardware.
For me, I noticed the application wasn't shutting down correctly, and was still listed in the task manager. Check there that your application isn't still running in the background when you think you have closed it.
Cheers
ow.

Hi,
Yes, I checked the task manager, and turned off ALL programs.. the GPS-icon was still showing in the icon-tray..
I don't think it's a big problem, because I don't use the GPS all that often.. but a little annoying..

Garmin
I'm using Garmin Mobile XT, Version 5.00.20wp, and is working well.
My ROM is 1.36.410.1 PTG.

GPS works great!
I've tested a lot of PNA & PDA devices with GPS and I'm very very satisfied with the GPS function on HTC HD mini, it works absolutely great! Finds satelites very fast, faster than some PNAs even it uses A-GPS. This can be problem when you are in roaming zones, for that, I use application DATA CONTROLLER (you can find it here in some forum).
I use iGO8 navigation software, with costumized DATA.zip archive, it works fine and I like it very much. Also iGO Primo is great solution.
HTC HD mini has totally satisfied my needs!

Hi Piona,
I was working several years ago with devices + external GPS units and devices with GPS inside (Pda, Notebook, smartphones,..)
I was working with GPS units from several manufacturers, kinds and versions (BT, serial, CF, SD, cable...).
In fact, several months ago, I was talking to HTC to know what is the brand what they included (Sirf,...) because it is a very interesting data to know if it works fine or not, in advance.
They did not confirm me this question but they informed me very good and send me tech. information in order to warranty a good perfomances.
Later, when we checked a couple of terminals (HTC mini) here, I could see is the best GPS what I checked.
Of course there is people with more experience than me but I can confirm you I invested days and days to check this question during a lot of years and GPS units and it is the best one.
It is a real GPS working in COM4 (Nmea, 4800bps)(remember it if you need to configure any software) but, the most important for me is it is very stable.
In short: fast, strong signal (I can work inside my office) and very stable.
Upon my point of view, the GPS is a very good argument from this terminal.
Have a good day

The GPS signal acquisition of my HD Mini is poor in comparison to my previous HD2. It can take 3-4 minutes to get a valid fix whereas the HD2 took only a few seconds.
This may be software related as I think it was better when I bought it, but until we can get the tools to update the Radio ROM I can only think of doing a hard reset to see if it improves.

My HD Mini (bought from Clove) came with a free copy of NDrive on a Micro-SD card.
It works very well. I find the HD Mini usually locks onto the satellites quickly when outside and holds that lock for longer, where my previous Sony Sat-Nav lost signal in the same position, in the same vehicle far faster.
If I had a criticism of NDrive it would be that it will sometimes instruct me to 'keep left' when what is really meant is 'turn left'.
Having said that recalculation of the route is almost instantaneous, it includes safety camera alerts and warns if I exceed the given speed limit for the current road.
I'd certainly recommend it and would probably buy NDrive next time I needed to.

I've now upgraded my ROM though still no new Radio ROM, but since then it has been far better. Fixes in about 20 seconds now from warm start.

GPS works great on HTC HD Mini.
Garmin mobile XT works like a cream.
Miero Via GPS Black edition is another one.

@ people who have the gps icon not removing itself as a status icon...
I myself have this problem using third party GPS navigation software...
try using google maps app after... then close google maps app ... with me this shuts down gps also...
Best of luck..
Joey

Garmin here also, flawless

GPS of HD mini is one of the best, if not the best. It acquires satellite signals and lock on very quickly. Even inside my office room. Takes seconds to lock. It out-performs the dedicated GPS device i bought earlier and installed in my car. So, now, the removed that device, and use my HD mini as primary navigation device.
I use NaviComputer instead of the built-in Google Map.
NaviComputer is a great app. It allows offline maps to be downloaded and saved on the phone. No need for internet access when i go out and use the phone as GPS device. This is a big plus, because in some areas -- especially in places when you most need to find your way back, GPRS/mobile internet is so weak and mostly non-existent. So that makes the wonderful Google map practically useless for me.

I use TomTom and also GPSTuner.
with both programs I haven't any issue

ozi
also oziexplorer works very well. I noticed it continues logging when the display switches off. this is really good for battery life!

[Q] Need advice for GPS

Any one can suggest a good incar mount for the TF101 ?
Also is there any app for gps (like tomtom) for the tf101, as i have read there does not seems to have any one made specificaly for the tf101 or any other tablet anyway ?

as i know, there is no gps aplication for the transformer ,because of the rasolution. But you can lnstall a software with the best rasolution, that there is,i think 800x480 and you will see the map only on a part of the screen...
For example i use IGO my way...

I have been re-using my old EEEpc 701 car mount for my Transformer:
http://www.ultimate-netbook.com/inf...h-7-inches-to-13-inches-ultimate-netbook.html
Works great and fits fine.
There are SEVERAL gps software solutions that not only work on the Transformer, but take advantage of the full resolution. I don't know why people think there aren't any for tablets?
The one I use: Copilot Live Premium (Europe). I've been driving all over the South of France and back to Belgium just last week. It's great if you can keep the reflections to a minimum.
Google navigation works great, if you have a portable wireless hotspot (ex: mifi), or if you download the itinerary before going, or if you tether it to your phone. I tried all of these successfully.
OsmAnd+, NavDroyd, will work at full resolution.

Both Sygic and Navigon are optimized(fullscreen) for Honeycomb.

Navigon is marked as incompatible with the TF101 on the market. Last time I tried it, there was no way to get the menus up on HC. Has there been an update that fixes this?

Sygic is a great product but does NOT work on the transformer - it works only on 2.x. I have it on my phone. Compatible devices: http://www.sygic.com/en/android:compatible-devices
I don't see a single android 3.x device on there.
There was a thread about Navigon a while back: http://forum.xda-developers.com/showthread.php?t=1079369

For first tests the free Navid might be worth a try. I myself used MapDroid and Google Navigation for first tests.
Because MapDroid only shows your position and has no rooting cababilities, I'm searching for a nice offline navigation app for both my TF and SGS2.
How satisfied are people with NavDroid? Should I invest more?

I've purchased NavDroyd in anticipation of having to travel in several countries in Asia, where my normal GPS navigation software won't work for lack of maps or licenses. I haven't tested it on the road, but I have played around with it from my couch.
There are several problems using Navdroyd, but to its credit, it's the maps that are mostly the problem - not the software. The maps themselves come from the wonderful Openstreet map project, a collaborative wiki style world map that anyone can use and contribute to.
Main problem: in non Western countries, leave the big city centers, and you might as well ask the locals for your way - the maps are sometimes very incomplete. A lot of the data is contributed by individuals that have uploaded their GPS tracks on the site and have themselves typed the street or city names. Again, not NavDroyd's fault.
Osmand, Osmand+, Mapdroyd, Osmdroid and so on - all use the free maps from the Open Street Map project.
Quite frankly, I think I will most likely stick to Google Maps when in remote places. It won't offer navigation, but with the ability to download a 10 km radius map, and having studied the maps and the sites/itineraries I'm going to use, it should be more than enough.

Sygic is a great product but does NOT work on the transformer - it works only on 2.x. I have it on my phone. Compatible devices: http://www.sygic.com/en/android:compatible-devices
I don't see a single android 3.x device on there.

**Sygic does work on the transformer.
I was looking for a GPS app that works well offline, with good route adjustment, and this is the best I've used. NavDroyd took a while to get the maps and then couldn't find a GPS signal, so I moved on and didn't really test the product. Copilot looks good, but the USA map pack was over a gig, and I only wanted one state. It's possible you can choose individual states, but I didn't get far enough to determine this.
Sygic, for me , works perfectly. Can pick which states you want to download. I'm pretty sure they even use TomTom maps. You get two apps, one to download the maps and the GPS app itself. Lots of choices for voices (U.K, Australian, American English's in male or female, as well as many languages). The UI could possibly be better, and in the menus the very bottom of the screen is cut off, but half of the buttons (usually back or okay) still show so there's no problem. By this I mean only the lower portion is cut off, not half are missing, if that makes more sense. The maps are great, though sometimes cluttered with gas stations or other useful landmarks (these can be turned off). During navigation your MPH (or whatever unit you choose) is on screen, with ETA, time until next navigational action (exit, turn, etc.) and even the speed limit. The voice gives warnings usuall at 1 mile prior, 2/3 and then gets almost annoying so you don't miss the turn (probably adjustable?).
I'm probably forgetting some stuff, but this is exactly what I was looking for. Never have to touch it so I just set it in the passenger seat and turn up the volume. Might not be the best out there, but I don't have any complaints so I stopped looking.

Sygic,Navigon,Copilot all work just fine in full screen(menus and everything) on the Transformer.
I know this because i tried all of them. Do not know about other apps but these work like they should.

I'm interested - how do you install sygic on the TF? Is it the official version?

To be honest, I started just downloading the apps offline after the first two, as I wasn't hopeful and wanted to test them first. I like to tell myself I'll buy the real version, but who knows.
It's possible that it wouldn't allow you to purchase from the market since it's not officially compatible, but I do not know. In any case side loading the newest version is what I did. Not sure if it was a cracked apk or not. Also can't remember if I had to sign up for an account, but downloading maps and everything worked fine after installation (and was free).

Google Navigation is pretty good. If youre in the car just use the phone as a mobile hot spot. You have a lighter, get a car charger plug for the phone so it doesnt die and use it all of the way.
Im looking forward do doing something of the like while driving up to visit my grandparents in the near future. Road tripping with internet, its the future!
