Well, first off let me say I have just upgraded from iGuidance 2 to iGuidance 3. iG 3 is about 8 MB bigger than iG2 and therefore I had to install it on my mini SD card. It works perfectly fine, loads seems to be just as fast (since maps are stored on the mini SD with either program. Anyway, my problem is basically that the program works great, but when the lady comes on telling me when to turn, lets say in 2 miles...it is REEEEAAAALLLY slow and exhagerated. She goes like, Turn.........left..........in........two........miles...... I recently started overclocking my 8125 to 260 MHz to see if it was a speed issue, but no change as far as the sound goes. Any ideas?
turn off your internet connection and you should be OK

IGuidance 3
Runs fine for me, at stock speed, program and maps on the mini-SD. Maybe it is the overclocking?

I have Iguidance 3.0. Now I need the GPS module.
Which GPS module do you all use? What is the best now? Holux, Globalsat? or some other.
Thanks

I tried it at stock speeds and overclocked speeds, it still did the same thing. I'll try turning off my ActiveSync with my Exchange later today when I'm going on a small road trip and see if that solves the problem.

I use the Holux GPSlim 360 I think it is. The number may be off though. It's uber small and I just throw it in the center console in my car and use it when necessary. Cold start is about 30-45 seconds.
The Rikaline GPS-6033 does not show to be SirfIII. I thought this is the latest technology to get. Is this a more recent technology or is the SirfIII over blown?
I brought this to the attention of iNavcorp, makers of iGuidance, a few weeks ago. This was their reply:
"Our programmers are currently looking into this issue. In the mean time, while turning off the phone will resolve the issue, based on our knowledge, you should be able to simply disable the gprs (wireless data connection) function on your PPC phone which will also resolve the slow voice issue, but this way you will still have phone access."
I had told them that turning off the phone solves the problem. Anyway, they are aware, and I am hopeful that they will fix this in an upcoming patch.
p.s. DNO's answer was right on...

It is the GPSlim 236 and it is a great unit! I love mine.
The voice on mine works great, I could not get it to instal to the SD, I had to install the CAB there, and then run that to install the actual program to the phone. My problem is that the maps haven't been updated with streets that have been made in the last few years, and the shopping POIs arn't that great.
I have a Houlix 268 slim (I Think thats the model), and it randomly loses connection, so I have to power-cycle it and restart IG3, for it to regain connection.
Also every once and a while it does a wierd click sound when I'm slowing down.

I did notice this was the issue this weekend. Is there a "quick" way to disable GPRS? I guess i'll keep an eye on iNavcorps website.
Turn it off from the comm manager. Mine works fine while I am using BT for my headset and on the phone talking.
Do iGuidance do maps for Europe? THey seem to have discontinued their european product; if I can get the europe map from v.2.12 will it work with v.3.0?
Cheers.
Loving my new O2 XDA Mini S, and am gonna get GPS SatNav thingy for it - I can get a 2GB Mini SD card for £25, but can someone recommend a good GPS Bluetooth receiver that works well with it (I'm in the UK). Is sirfIII better than sirfII chips? Do I need 32 channel or is 16 fine?
Also what software do you guys recommend? TomTom? iGuidance? iGo? All I'm really interested in something with spoken directions and something that lets me type in 2 post codes and Go!
What version of TomTom is applicable to the XDA Mini? TomTom Mobile? TomTom Navigator?
Is 6 worthwhile or is 5.21 ok?
Is it easy to install?
Sorry for all the questions, just excited about the prospect of SatNav
Hi there, welcome to the world of the Wizard, :lol:
As far as GPS chipsets go, I think the SirfstarIII is better but I can't be sure.
I always got on very well with a 16 channel BT GPS before it broke so dont be fooled by loads of hype about how many channels it has.
More channels does mean it can lock on to more at once but it isn't absolutely necessary.
Tomtom 5.21 is good enough but I feel personally that 6 is better. Bear in mind that if you would like TT on a landscape setting, it doesnt have that feature anymore so 5.21 is the way to go. Other than that, there are ways around it, it's up to you.
Hope that helps a bit

Sorry i disagree with that, it may not have it i the programm but i have my mic button set to switch between Land and Port. I just press that button and it works good in land!!!
To set a button Start, Setting, buttons, select you button at 1. and then select <Rotate screen> at 2.
and now you have landscape for Tomtom 6.0
The holux GPSlim 236 is a very good device, Sirf III so great reception and its tiny.
as has already been said, more channels isnt better, while there are loads of satellites up there due to the curv of the earth you will NEVER get more than 10 sats at once, Ive had 9 and thats the most my device sees.
You also only need 3 to get a lock. 4 gives your position in 3d (so altitude as well) and more doesnt really do much. So any 12 channel reciever is good. But yeah, aim for SIRF III, the quicker lock on and better reception in built up areas is a must.
Im currently using Tomtom 6 and its the latest and greatest. If your getting tomtom then obviously get 6, its actually cheaper than 5 (even cheaper if you know where to look )
I tried route 66 but its too much, Im a techie myself but this program is just stupid, giving you all sorts of useless info on screen and very little map.

Disagree with what???
And on that score, if you want to sacrifice your recording button, the next option, "Button 4 (Hold)", assign that to the Tomtom Navigator program and hey presto.
Yes, I have "purchased" TomTom 6 already at an, erm, "good" price, with GB maps.
I'm gonna get a 2GB mini SD when I get paid, and a GPS receiver.
So am I right in thinking ANY Bluetooth sirfIII receiver will do?
Also is it easy to set up? I've read some scary (to me anyway!) stories about registry hacking etc on the XDA Mini S to get it to recognise GPS receivers.
Paiting a BT GPS is easy - just ensure that the name you give it ends in "GPS"..... then TomTom will connect to it .
That was valid for 5.32 - haven't tried 6 yet..

To answer the question, the pda version is Tomtom Navigator.
Mobile runs on 'phones'. By that I mean units that do not have a touchscreen.
Well thats my interpretation anyway. I have Tomtom 5 Mobile on a Nokia 7610. i.e. It doesn't have a touchscreen.
I decided to purposefully disregard price for the GPS and got a USGlobalsatBT359. It cost £75.
The reception is fantastic. I can get 8 or 10 sats at high strength if I stick the unit on the underside of the car roof. My TomTom Go barely picks anything up.
The start up time and battery life are great. Just needed to tweak the WM5 registry of the Vario2.
The only thing I don`t understand is the GPS control panel!!!! It does not seem to do much!!!!

What i've done on mine is assign that button to the voice commander thing so I can run multiple actions by voice by holding in the button.
Not perfect but I found that assigning TT to just one button then left me wanting other things at other times.
David.
I have a Holux (not HOLOX - cheap copy) 20 channel BT GPSlim 236 receiver which is great. A 32 channel receiver may well mean you stand a slightly better chance of picking up satelites but there isn't 32 satelites up there anyway.
The system works by triangulation meaning you only need three to get a lock on your position. The more you see the better though as the lock will be stronger. Many will tell you that due to the curvature of the earth you can only ever pick up 6 satelites maximum, but I happen to disagree.
Tomtom 5.21 is great, got it the other day and I found my way home first time... lol.!
Matt.
p.s Don't forget that GPS works using US military satelites, so if the US feels a bit twitchy i.e. either someone is about to pick on them or vice versa then they can change the coordinates of the satelites meaning over a distance you won't have a clue where you are!!

Yeah it does but you might not need it.
Say you've got TT talking to the GPS on COM7, that's fine until you now need another app also talking to the GPS at the same time. It can't because the GPS is already talking to TT like a pair of housewives that haven't seen each other for, oh about a day! (ok, nothing like a bit of evil stereotyping eh?).
What the GPS control panel lets you do is share the GPS between multiple apps. You configure the GPS CP to talk to the real GPS via the hardware port number and then create a software GPS port.
You now configure your apps to talk to the software GPS port and the GPS port driver abstracts the real GPS port and sends the data to all the interested apps.
Like I said, you might not need it unless you want multiple apps to talk to the GPS at once. Why might you want to have multiple apps? One example could be a track data logger running at the same time as the satnav.
Or another might be Wififofum doing a wifi wardrive at the same time as running Tom Tom for satnav.

I got the same bundle and I love it.
looks like some people have had problems with teh Houlk 236 over at gpspassion.com
I just got a Globalsat 338 and its awesome!! Huge improvement over the SIRFII based CF card GPS I had for my old ipaq.
I also 2nd iguidance. Its cheaper than tomtom5. I don't know which I like more, they both different things well (but Iguidance sure loads faster than tomtom for me). I'm looking forward to trying tomtom6 to see if its a huge improvement
looks like some people have had problems with the Holux 236 over at gpspassion.com. Might have been a bad batch but I steered clear. Hopefully no one here is affected by them.

-edited because I type like a 1st grader
I would never buy Holux ever there technical support is arrogant and rubish they turned round and said sorry we dont support the item unless it was purchased from the uk
And would not send me the firmware to flash my gps230 so its now sat in a drawer doing nothing and i have a cheap £40 one thats brilliant BT-GPS

I used TomTom 5 and now Version 6 with no issues at all. I've seen co-pilot live 6 up and running and I'm very impressed with that too, but TomTom has never let me down before, so I'd recommend that.
i 2nd tomtom navigator 6 (apart from the lockup sometimes when it sarts its great)
I'll give that a shot - thanks much! It's pretty pricey but it looks to be the best out there!
Tomtom 6 seems to do the job.. expensive though, very old maps in some cases, people in the US have been *****ing about it doing silly things.
Here in australia though, no problems so far. Although I'd like a map update to tell it of some local changes..
i am using tomtom5. it's ok, although sometimes it hangs the hermes.
Best GPS software depends a lot on your location; because of it's obvious purpose, the most important things are area coverage and maps quality, then comes the interface, POI management and so on... Tried TomTom Mobile and iGO and stuck with the latest, because the maps are far better and precise (in Romania where I live).
For off-road I use GPSDash, it has all the features some might need + the posibility to create user maps.
Entire USA in 1GB microSD w/ OCN5
Any body tried OnCourse Navigator 5 on their TYTN? I think this GPS software blows TomTom away w/ seamless USA fitting in 1GB microSD. ETA,elevation,speed displayed in 3D mode, map refresh rate of 4fps compared to the usual 1fps with the other usual display-(like time and next street to turn)
I just hope it is compatible with the Tytn...
Try iGo Europe 2006 (http://www.i-go.com/en/products/iGO_2006_SD/screenshots.php). VERY FAST and has less problem than TT. It also has better graphics.
The downside is that the POI listing sucks. If I search for McDonald's around my current location, it'll list those from 100 meters to 50 kilometers! The software enough to know I won't drive that long from my current location just to get a fries.
Well, I got Tomtom6, but my GPS unit that was supposed to be shipped to me today was reported as out of stock - so sounds like I'll be waiting a few more days to try it :/
I use the Garmin Que software with a Garmin GPS10 receiver. Works great. I own the North America maps as well as the Europe maps. Have used them extensively in NA and in the UK - very happy with the combo.
When I researched the options, the above combo was rather cheaper than the TomTom option.
If TT works then most other software will work too.
I've a few other programs I'm going to test to make sure they work but assuming they do then I'll have the folllowing installed and to use:
GPS Tuner
GPS Auto
VisualGPSce
Memory Map
Navigon Navigator
try mapopolis
mapopolis has a free demo. at 99.00 it is cheaper too.
I've been using it for a year on my harrier, and now on my 8525. Works pretty well on both.
I use an I-blue gps. sensitivity and reliability is very good, mini-usb charger is non-standard pinout though.

Indeed, however, not unless you already own the software
the software is free to download. you pay for the maps only. to download the app, go to demo maps and the first step is downloading the app. the demo maps are short lived, but full function. I think you can keep downloading them over and over when when they expire.
iGuidance v3.0.1. It is excellent!
Everybody says "tom tom" because it's the most common name. After doing my research I settled on iGuidance and could not be happier. Good luck.
I'll definitely have to look at that too! My GPS unit is backordered... I'm still waiting on it ><
The problem w/ iGuidance is that you cannot fit the entire USA on a 2GB microSD. Map file is 2.5GB

Hi there,
i am running tt7 on my Asus P535 with WM 6.
I have this problem:
TomTom is always about 200 meters behind my actual position. I think this is so because of an not well resolution. Only if I drive very slow (about 30 km/h) tomtom shows my position correct.
I tried all versions. Repack 3 qvga, qvga... 7.450,.. 7.541...but each version came up with the same result.
Is there a possibility to stop this annoying lag ? Or do I have to cope with it. Did anyone else notice this , also?
With TT 6 (6.032) this problem never appeared.
If you're using a bluetooth reciever it sounds like it hasn't got many channels. More channels better reception - more accurate.
If the phone has gps built in then check the position of the phone in the car. It needs a clear signal to work properly. under the windscreen is best, not on the seat beside you.
Otherwise it sounds like memory problem. Other apps using ram and limiting how much the gps program can use. though most of the time when I had that problem it just kept jumping all over the place.
You have to slow down, you're driving too fast
You can also try turning off points of interest and any info you don't need. Even street names can make it laggy.

I don't think it's Tomtom's versions problem... it's the GPS signals likely
If you don't get a good signals or number of Sats yo will be far from your real position.
Consider if there are alot of obstacles which would cause or interfere with the signals:
- Tall buidlings, trees, objects
- under ground car park, buidling
- Metals (depends)
- Raining and not clear sky
- Other devices or in a high EM
- GPS chips got faulty
- Firmware or memory that store calculate functions got problem
- Not enough numbers of Sats
- ...
Hi again,
I don't think it is an GPS Problem.
I have an built-in- GPS- Receiver and I get between 6-11 Satellites.
Another user (he has the Diamond) had this problem, also. But he took the wrong tt7- Version. After using the right one everything was okay.
But it also might be the processor of my P535 ? Might that also be possible?
oh, I got about 18- 20 MB of RAM free

Have you tried using iGo or other GPS apps and experienced similar lag ?
Even on my old Wizard TomTom7 runs without problems.
Have you tried it in another car, or outside your car? Maybe your front window has a special alloy to prevent sun emission. Know this problem of some of my friends, they have had this problem (Mostly on new VW,Audi,BMW i know this problem, maybe other cras have something similar).
Hello,
I tried many other GPS-Systems. Navigon, IGO, MIO,Garmin, tt 6. But this 100-200 m lag appears only with tt 7. And this was all in the same car.
I have no ideas anymore what this might cause this.
I know, my P 535 is not the latest one but it still has got a 520MHz Intel Xscale..
It is not the map, also. I tried 3 different tt 7 maps already..

As was mentioned above by snachez, I believe it's the amount of poi's you have showing on the screen while driving. I had the same problem with about 20 poi's showing. When I turned it down to about 4 poi's, the problem went away, and now it's SMOOTH as silk.
Hope this helps!
Sorry to chip in here. Seems like you all here uses GPS. I just bought a new PDA. MWg Zinc II with built in GPS. As I am living in Singapore, I would like to know is it possible to obtain igo Singapore map for free? GPS maps are very expensive and I would like to know where can I download it and use it as a full version without paying.
I have been using windows mobile devices now for about 5 years,my first phone was an mda compact III which was excellent.next up was the Mda Compact 5 which also is a very capable device, might I ad these 2 devices were brilliant with the sat nav never missed a beat allways having plenty of satalites ,my main reason for having these windows mobile devices is all in one phone and sat nav as I am a driver and sat nav is a MUST .I allways have the latest version of Tom Tom navigator installed on my phone. This is when I started to get fed up with touchscreen phones as they can be so annoying with wrong finger scrolling and such likes, I decided I now need a device with physical keys.
This were my search for qwerty keyboard phone began,firstly I bought the Samsung i780 which on the face of it was a fantastic device it was solid,fast ,However the gps was just awfull I loaded up my tom tom but I tried in vein to install endless apps like gps test /gps gate,etc etc and just could not get it to work right,
Next up was the I-mate 8502 again another nice device but 10 -15 resets a day all got too much and that went also.
So here I am with the Palm Treo Pro ,managed to get a nice example from Ebay for £70,really nice device loads my tomtom 7 with 850 maps on no problem,really likin the phone ,I think I have finally found a phone that will suit all my needs ,spb mobile shell to get away from the home screen and I`m away. First day using the Phone with the tomtom on and the the phone freezes on me twice ,soft reset sorts it out .,I have read endless amounts on this since then with no conclusive remedy.IS THERE AN ANSWER TO THIS PROBLEM or is this fine phone going to be a non starter,I will be so disapointed as i really enjoy using this device,all help or comments will be greatly received.
Thanks in advance.
well if you have a data plan, i highly recommend getting google maps. otherwise you could try bing. both are very good applications and save you a lot of space. sorry im not familiar with tom tom, but i do know that there is not too much ram on the treo. if you close all your other applications in the background, you might get it to work then =]
Thanks for your reply .Think I have found a remedy to the tomtom freezing daily,I changed the baud rate from 4800 to 9600 and so far no more freezing and losing sats,only been 2 days but no more hang ups.

Hi, if u don't mind shelling out some more money i would recommend u try Garmin's navigation software. I've been using it almost daily for about 6 months with fast gps detection rate, etc, and it has never frozen up on me. and as computerguy pointed out, it works best if other applications in d background are exited.
P.S. I'm using a custom ROM though.
I'd second the Garmin software. Used to run the TomTom software on mine and had nothing but troubles. It would either freeze up or just would lose the GPS signals constantly. Garmin might not be as nice to use but its rock solid in comparison.
I agree about TomTom freezing. I don't have it as often as you do but I do have occasions where it seems to lose all track of where it is.
I have switched to Sygic MM10 and it's brilliant. It uses the same maps as TomTom but has better graphics and is rock solid
