Hi,
Like most people here, I've experience TomTom's lag. From my stock Touch Pro, I notice a 3-4 second lag whilst driving around 60km/h. I read the previously mentioned GPS tweaks for the Touch Pro and initially applied the tweaks, but only dividing the original values by 4 (eg. PollInterval went from 1024 to 256, etc.). This reduced the lag to 1-2 seconds whilst driving. After applying the tweaks by dividing by 8 (eg. PollInterval to 128) resulted in the same 1-2 second lag in TomTom whilst driving. Clearly, the GPS is no longer the bottleneck now.
Next, I planned a route and watched the Demo at 200% speed to see how fast I can expect TomTom to appear. The display refreshed every 1-2 seconds! Coincidence?! I was in Harvey Norman (huge electronics retailer with lots of demo units) and watched a route Demo on a TomTom standalone device at 200% speed. The display refreshed 2-3 times per second.
Hence, is it possible to increase TomTom Navigator's refresh rate on the Touch Pro? For example, by applying some kind of graphics configuration changes or something? Perhaps tweaking the graphics driver somehow? Or is it that the standalone TomTom devices have much better hardware and the performance we are seeing on the Touch Pro is about as good as we can expect it?
Any help appreciated!
Cheers,
Ledg3.
Any ideas? Anyone?
Just wondering. have you tried one of the newer roms that have the gps driver cooked in? i am using provens 1.06 and it seems to not lag as much (only tried it for about 15 minutes earlier today)
Hi ajmoncrief,
Thank you for your reply.
I haven't tried any ROMs at this stage as I received my Touch Pro just recently.
Is it possible to load the new GPS driver without replacing the ROM?
Also, does your new GPS driver lag less than 1-2 seconds whilst driving?
At the moment, I would be surprised as TomTom only updates my display every 1-2 seconds, even just by running a demo (and not relying on the GPS for input).
I'm not sure about a driver cab...I would assume that theres one floating around. Check out Da G's rom thread and qsqa's PROven's thread. I tested tomtom again this morning and I'm getting much better results now. I'm not exactly sure how fast/slow the screen refreshes, but it does do so in a timely manner. Im confident that it does do better than once every 1-2 seconds. (I only live 3-6 miles from everywhere I need to go and I dont have any out of town trips within the next couple of days) Maybe someone else can chip in on their thoughts here.
TomTom 7.9 slow refresh
I am having the same problem on the AMEO (X7500) and TomTom 7.9 - screen refresh is quite slow, every 2 seconds. Version 6 was running realy smoothly. Any ideas? Soft reset, restart, speed camera warning on-off does not change the refresh rate.....

Your position on the map is always going to be a second or two behind your actual position. There is no bottleneck or slowdown even if you set the GPS at 4800 baud. The GPS only sends out a position update once a second. This will also make the screen a little jerky. Most programs smooth out the jerkiness by assuming there will not be a huge change in speed and smoothly move you to where they estimate the next GPS position will be.
Some programs also cheat and estimate your actual position on the map, so it is very close to your actual position. You can tell, because in the city you will be shown going through the intersection when you make a turn. It will then jump backwards and then show you making the turn. One of the GPS programs I use to have did this, but I do not remember which one.
TT7 on my Kaiser (ATT Tilt) moves smoothly along, and is near dead on for location. There's no refresh problems.
TT7 on my Raphael (ATT Fuze) repaints the screen every 1 - 4 seconds, and my position is off by at least 100 feet. Even with tweaks, it functions pitifully compared to the Kaiser.
is everyone here using the VGA version of TT7 or the QVGA version meant for the Tilt?
there are different versions (vga and qvga)??????????
Have you tried Franson GPS gate? DOwnload the trial and create a virtual com port 2 and map the Com4 GPS multiplexer to virtual com 2 and then have tom tom look to com 2 for the GPS. I bet the lag goes away. I was told that the commercial GPS softwares look for standardized GPS info in which the HTC phones' GPS use a variation which causes lag problems.
tomtom 7.910 screen redraw problem
Yes there are different versions of 7.910.9185 blue, black qvga and there is VGA version. I have the problem with the screen redraw, not the general speed, which is better than 7450 for example for route calculation. Screen redraw on 7.450 version was running smoothly, so it is not the question of the GPS, but the maps form 7.910 are not compatible with the 7.450. Screen redraw problem is visible even in demo mode, at 200% of speed instead of the smooth ride you have a "slideshow" in 7.910 version

I was using 7.450 but i read that version was for qvga devices so i upgraded to 7.451 i know it seems stupid for a .001 update but that is vga not sure about 7.910 as i read that it was vga to and for the diamond if im not mistaken but you can try 7.451 if you want. look around for it also if the map works for 7.450 i don't think it will work for 7.451 or at least it did not work for me. so look for the files if you can't find them drop me a pm and i can tell you where to "BUY" them also i tried the gps reg tweaks and it did not seem to make it any better but i did not have a problem with the gps in the first place. hope this info helps
I've also experienced lag like what you guys are talking about... what I did was I disable all POI in preference so that nothing will show up and it seemed to be a lot faster... still has that choppyness... but much better than before... i hope this helps...
Anyone has this 7.450 Tom Tom VGA Cab? Thnx in advance

How sure are you about this solution? Have u tried?
If it works, it means TomTom is at fault here, and not HTC
But it also lags in Google maps....how would you explain that?
I am very curious if anyone has really tried this and can confirm the lag going away (and most important; make pedestrian mode usable)

Sadly the HTC really is fault here, not TomTom. I have a external SirfIII GPS module, and while TOmTOm still appears to redraw 2-3times a second, the lag goes away. And TomTom is very very accurate then. The Franson GPS gate doesnt solve anything with the lag. It might make GPS lokc quicker, but tbh it didnt help me much (using QuickGPS data). I get fast locks with both the built-in and the external GPS. The problem is between the data output and the chipset. Drivers should / or could solve it.
Problem solved!
Hello,
Yes I have been experimenting A LOT with TomTom. I have found out that what really slowes down the map redraw is the RADARS if they are inserted into the map directory as a POI. Without radars it runs very nice both in version 7.45 and 7.9.
TT redraws screen very slow even if you switch off the warning for getting close to the radars as POI categories, I think that it is much too many of them for the whole Europe and POI mechanism is not the proper one for radars. Changing the radars into the official "with serial" solved the situation. I hope it helps to the others!

How is Kaiser GPS performance in comparison to a "normal" SiRF Star 3 GPS?
I've heard different opinions on this, some say it has weaker reception, some say its equally good.
Personally after few days of using it looks alright to me + you get the a-gps for quicker fix.
Is it possible to show a screen grab AND/OR a photo of the actual device running a map application?
I use a VGA device and find it very hard to part with it...
let me know what exactly do you want to see and i'll give you the screens.
Tomtom? googlemaps? map? 3D navigation? you must be more specific
Here is iGo in cockpit mode. I'm in the house, so no GPS here but it should give you an idea
I'm working on a full comparison, but yes the good news compared to the HTC Trinity (see http://www.gpspassion.com/fr/articles.asp?id=175&page=6) is that A-GPS really helps shorten the time to fix in the morning and accuracy has improved as well. It still does not handle difficult urban canyon situations as well and tends to "lose it", but that would only happen in extreme conditions.
GPS lock times are amazingly fast for me compared to my HW6945. Started just now in my room and took about 3 seconds for a lock. Love it
Tomtom 6.032
iGo
Google Maps
im in the states and tomtom, live search, and googlemaps works flawless w/o having to install a "jumpstart" app. I prefer tomtom since the maps are preloaded so it doesnt have to use your data connection and also the buttons/screen are finger appropriate. When i load tomtom it finds satellites within 30 seconds and it will even work indoors most of the time.
I have just updated my ROM to "Dutty's WM6.1 Hybrid v2 5.2.19716/5.2.19700" and at the same time installed TomTom.
It can take quite a while to pick up a lock the first time the software is booted but if I close and open TomTom without rebooting the phone the second time is much quicker (almost instant). I have just tried rebooting the phone and it goes through the same slow process the first time tomtom is booted and then quick following that. Is this normal behaviour for GPS on the device (not holding GPS info when the phone is rebooted) or is it an issue with the ROM or Radio. If its the radio is their anyone in the UK who can recommend the best radio for battery life and GPS.
Cheers,
Michael

This is pretty normal for GPS especially on these devices. It takes a while to get the first fix after a reset, but subsequent ones are quicker.
You may be able to speed up this process by using the QuickGPS tool to download cache data of satellite locations.
Also, try and use GPSTest to get the lock first. Many people use the GPSTest application and keep it running in the background as it tends to keep a good lock on things.
Adjust the baud rate with GPStest.
cheers for the responses... i will try the GPSTest thing...
KDKobes: what change does adjusting the baud rate make? quicker to lock?
I'm running the new, stock 6.1 Rom, and the only criticisim I have of it is the really slow initial GPS lock. The first time I use it after a soft reset or reboot, it can take anything in the region of 10-15 minutes, which I really don't think is right - I'm positive the original Rom was better at this. Subsequent fixes are much quicker, but if you find yourself needing the GPS and you happen to have recently rebooted, chance are you'll be well past your destination by the time it picks up, which is not good.
Quick GPS appears to be behaving as it always has - whenever I check it has recent data showing, downloaded through Activesync as normal - but it's almost as if that data's not being used in this Rom.
I should mention I'm seeing this behaviour in both Tom Tom and Live Search... it always does get a lock eventually, so there doesn't appear to be a problem with the GPS itself. Has anyone got any insight into this?

The baud rate is used by the internal COM port to interface with the GPS controller. It is the same deal like the speed of a modem...2400....4800...9600, etc.
Honestly with the amount of data that a GPS passes (which is not that much) I don't know if it makes a difference if it is set low. However, I always set mine high because faster is better, right so, might as well.

Where would you even set that though? I played with GPS Tool for a while, but it appeared to forget whatever port setting I used next time it ran anyway, so presumably it only affects that session of GPS Tool, not the system as a whole. In TomTom there's no speed setting for the internal GPS either; it should all be handled by WM itself.

Yeah, I think that's right... you can set it inside GPSTest.
However, like I stated many people find that GPSTest gets the quickest lock and prefer to either open it first and/or leave it running in the background. I haven't used my GPS that much, but I do find that this works.
It at least allows me to see what is going on with the lock. If I start Google Maps it will either work or not with GPS, but not really show me what's going on. GPSTest will allow me to see if I have a lock or not and then open up my other apps for use.
I just realised, I'm talking about the HTC GPS Tool, while you're talking about GPS Test - which is that, the Chartcross one?
You should try IGO8

Hello!
I have experienced exactly the same problem as you have with TomTom.
I have both a "Tytn II" and a HTC Advantage (X7500).
When using TomTom on the X7500 the GPS takes time to fix a position, 15-20 min or more is not unusual after a soft reset.
Then when it has fixed the position it is EXTREMLY slow when it comes to calculating the route!
I live in Sweden and I often drive to Germany, and when calculating the route from Sweden to Germany it takes over 3 min to finish!
Then we have the issue with the struggling graphics, (Of course I have been told that TomTom has trouble with VGA displays, and I find that to be very true.) the map is very slow and sometimes it stops completly for a few secounds!
On my Tytn II however the map is not struggling the same way, and it calculates much faster then on the X7500, Why? I dont know!
X7500 is a much faster device so it beats me!
The GPS lock is however almost as slow on the Tytn II as it is on the X7500, no matter if I have used quick GPS to download data or not!
A few weeks ago I stumbled upon a navigation program called IGO8, I decided to try it, and believe me when I say that I will never go back to TomTom again!
First of all the GPS lock is almost instant with IGO8, from a soft reset it finds a lock within maybe 2 min at most! And then it seems that it somehow remembers the position and the next time you start the program it will have a fix in secounds!
Then it calculates much faster, I tryed to calculate the route from Sweden to Germany on my X7500 and it was finishes under 20 secounds! (Compare that to over 3 minutes with TomTom on the same device!)
It supports VGA screens, so the map floats much better on my X7500.
Next thing is that there is more maps for IGO 8 so it covers much more of "mother earth" if you want to navigate in a foreign country!
It also has 3D terrain, and can even show buildings in 3D! (Only works in some places!)
It has a very simple and logical interface that is much easyer to understand then TomTom, and it is skinnable and very customizable!
So if you are serious about having a great navi I would strongly recommend you to try IGO 8! I can promise you will not be dissapointed!
Oh and buy the way, I dont work for IGO either!

I have problems getting software on my O2 Stellar to recognise the internal gps. I've tried a couple of different programs (TomTom & GPSTuner) and also fiddled around with the com ports in both the software and on the Stellar (using the External gps app in settings) but still no recognition of the internal gps.
I caleed O2 and no one could help, in fact they didn't even know it had internal gps!
I've seen GPSTest mentioned a few times. It's not on my Stellar - where can I get it?
Am I missing something?
Help please!

Get GPSTest here
You can either manually set it to a COM port or have it autoscan. I believe some ROMs identify it as COM3 and others COM4, so probably best to do an autoscan. It might take a few minutes to find it, and then another few to get a lock. But after that it generally starts up and locks within a minute or two (in my experience).
Hi everyone,
Have anyone noticed the slow calculation/refresh rate of GPS once it's active and navigating? Hold it in your hand and walk, there will be no refresh rate at all ! Your speed will be at 0 km/hr and the co-ordinates will not change at all. If you are in a car and it's stand still or on a traffic signal, or if there's a traffic jam and you are standstill and very immediately you have to turn right/left, you are sure to lose your way since it takes some time after the vehicle is in motion already to calculate and refresh your actual position and speed. Even when you are driving, there's a constant slow refresh rate of around 4 seconds. i.e. say you are accelerating the speed of your car, notice the speed being shown on the GPS software, it'll show your actual speed at a delay of 4/5 seconds. Same goes when you apply brakes, your speed suddenly goes down but the GPS will take it's time to reflect the correct speed.
I must say I am very disappointed with the GPS performace since my last phone was Trinity, it's GPS chip is just normal/ no agps but it's performance is much better than diamond's GPS. Trinity's GPS is immediate refresh rate with no such delays at all.
Test your diamond GPS observing what I said in this post and please post results here.
Are u sure it`s GPS issue not an software one ? Which software do you use for navigation ?
It's not a software issue since I've used TomTom and Garmin MobileXT with same results.
Same issue here!
Plus, the serial port keeps disconnecting of the internal GPS receiver keeps on disconnecting...
Which radio version have you on your device? This for sure software related (firmware, GPS navigation software or drivers)...
HastaSSSS
Have you enabled the AGPS on tweak? I found with this on the port would consistently connect and disconnect. Plus the refresh rate on TomTom was very very slow either driving or walking.
Today I turned AGPS off as where I travel it's not really needed anyway and bam!
Refresh rate both driving and walking is as good as my TomTom unit.
Today I drove with them both on and they were virtually in sync on the maps and spoken directions all the way. Very pleased.
Oh and ensuring "Receive all beams" is off in connections can help with TomTom too.
My details in case this has anything to do with it...
ROM : 1.37.405.1
Date: 10/06/2008
Radio: 1.00.25.03
Protocol: 52.26a.25.09H
And can you change the gpx settings under WM settings?
Even if I try to change the baud rate, when I go inside the configuration file, it's back to 4800 again...
HastaSSSS
This is a common problem with modern GPS chipsets - the way that they reduce multipath interference (from tall buildings, etc.) means that they often ignore movements below a certain speed (which can be often higher than walking pace).
Assuming that the HTC Touch Diamond uses the SirfStar 3 chipset (does anyone know for sure), this problem could theoretically be reduced by altering the 'static navigation' setting (see point 4 in this post for more details on static navigation and why it results in poor low-speed accuracy). However, how you'd actually tell the chipset to disable this feature, I don't know...
On an unrelated note, I have to say I'm extremely impressed with the sensitivity of the GPS chipset in the Diamond - it's managed to get lock in the middle of the my house, which is an amazing feat, and not one I've seen either my MTK or SirfStar standalone receivers achieve.
I am also pretty satisfied with the GPS performance. Can't complain on that!

It's a good theory, no doubt about that, but I think it's more a lag in the communication between the receiver and the phone, or a lag on the rendering of the map.
Your explanation doesn't foresee as well the reason why the connection keeps falling...
But I've learned already something with your post. Didn't knew about that "feature" or "characteristic" of the SIRF III receivers.
HastaSSSS
My experience with the Diamonds GPS is 100% better than on my HTC P3600.
I primarly use the GPS with google maps in Canada, and Jamaica and it gives me accurcy to about 15 feet.. where with the 3600 it was accurate to about 30-40 feet. Normally have about 7 to 8 stats connected. Didn't touch any of the default settings on the phone.
I also tested with Live Search and GPS tuner v5 and works perfectly. Fast lock times (5-10seconds)....

If that's true according to the static navigation thing? how can we disable it on our diamond? Can somebody throw a clue?
About AGPS, I haven't enabled it, or it's enabled by default in the new rom? 1.37 one?
It's like this with even AGSP disabled so it's certainly not the AGPS which is causing this delay in reception.
After googling and studying, i've found out that it's indeed the STATIC NAVIGATION which has been enabled by default on the diamond chip. Somone have any idea how to disable it? Please share
nice to see that I m not the only one with that problem, I was asking myself if it was my device who was deffective. On my cruise there was no lag at all.
I took mine out walking today and noticed it was telling me I was stood still for about 30 yds.
So I took it and my standalone out and the Diamond is rubbish but my big tomtom unit is great!
What's the point of GPS in a handheld device if you can't use it walking?
I hope this is easy to remedy.
I'm pretty sure that they don't use SirfStar III which would present much better GPS performance. Most probably they just incorporated the GPS section in the Qualcomm processor. Of course you can buy a SirfStar III Bluetooth receiver, but it doesn't make sense if you already got GPS built-in the device. I can only say that I was using HTC Hermes with SS III BT receiver a lot (more than 8 hours daily) and when I heard that HTC Kaiser had GPS build-in I was very happy untill almost immediately after trying TomTom on my new device I noticed worse performance. With Diamond it's the same story. Unfortunately...
A-GPS.
When I got the phone I installed the advanced config tool to adjust soms settings.
I also noticed A-GPS was off.
So I was thinking that turning it on might be a smart move.
Which it wasn't. TomTom reception was bad, waiting minutes would give maybe 4 sattelites en losing them constantly.
After turning of A-GPS again.. Whitin secconds .. I got 8 sattelites with a steady signal.
TomTom works fine for me now.
Excuses for my bad english...
for "foot" navigation the igo8 has a special setup along with "car", "bicycle"' "public transportation" and so on...why blame the diamond? blame yr navigation software! how many ppl said their navigation is the best? best, my ass the best.
be cool, soon igo8 is going to be avaible for diamond also
as for the diamond's gps...it works inside my house, first floor !!!
I really feel for you guys. GPS is one thing I definitely want to be working perfectly, and I can say with the diamond so far that has been the case. I'm getting a lock in about 15-20 seconds with about 12 satellites. I'm also using QuickGPS with no problems. I have been using the new TomTom 7 and it is absolutely fantastic!!!!!! Best handheld GPS solution I've ever owned, and I don't see why it would not be identical to a TomTom PNA!
My GPS is also not accurate, I'm using Tomtom7 and its telling me my home address is atleast 30 metres away when I'm at my home address. What the hell!!!!
I have tried enabling and disabling the A-GPS option and still its the same result.
i have the original rom (1.35.401 ) and radio (0.93.25) and igo 8 installed and i have a big gps lag (5 sec). Is it a problem of igo 8 or rom/radio? If i flash a newer versions it will help? Slould be a cooked one or original is enough?
This GPS lag problem has not yet been resolved by anyone. Let's hope some rom cooker are able to resolve this lag problem. There are apparantly many people sufferring from this
Hi guys,
You probably used ACT and enabled A-GPS.
You should disabled it.

You probably used ACT and enabled A-GPS.
You should disabled it.

Nope, thats not the issue.
A-GPS is disabled.
In my opinion the issue is generated by the interval between 2 consecutive positioning readings. It seems that somehow, the application doesn't receive data's from GPS fast enough and because of that, between 2 consecutive readings, you allready made 20-30 meters - enough to miss a crossroad . For example, because i also have a builtin car GPS, it seems that the IGO is allways ~20-50 meters (depending of speed) behind the builtin car gps
There are 3 options which can generate this issue:
1. IGO himself
2. Windows driver
3. GPS HW
For 1st option - i will try with a bluetooth GPS. Unfortunatelly i don't have one. Maybe somebody can try and let me know if the lag is the same?
Also if somebody can try tomtom (there are no available maps where i live) and let us know if still has that lag
For 2nd options - There is an option in registry called POLL interval which is by default 1000. I will try to set it to 300 to see if there is any difference. If is not maybe the dll has something hardcoded about polling interval
For 3rd option maybe with another Radio version the problem can be solved
Please let me know if somebody allready tried some of the options or have another ideeas
Hi there, I have GPS in my Parrot hands-free and it has the same lag as the bulit in GPS.
Seems strange that the Parrot has 2 times stronger signal (and about 2 sattelistes more) than Diamond And it even has not SIRF III chip!
So it is not 1)
Using TTN 7.45 and no lag

it's not 3) then - if you have the same lag can be related to IGO himself. So it remains 1) and 2)
possible solution?!?
I have / had the same Problem.
It could be possible, that several programs try to use the GPS-chip at the same time. In that case, it could be that windows switches the availability between these apps. At my Diamond this strange behaviour starts after taking some fotos. So infer from it, that the option of "GPS-Photo" could be the villain.
I switched it off with "advanced config" before one hour. And till now everything is ok. I hope it will last a while.
but on mine the GPS photo is allready disabled and it was never enabled
AGPS
Yes, i think i was wrong. Today in the morning i had the same problem, again. So i tried something else.
Disable the "Assisted GPS" seems to work. Since then i had no more problems today. Lets hold the thumbs!
i've tried another ROM and RADIO - the same issue
I can only say that you shouldn't expect no lags in GPS software. I was using a lot of standalone GPS devices like TomTom Go/One etc. and even they lag a bit even though they use SirfStar III chipset. You just have to get used to it. Of course, new ROMs may decrease the problem a bit, but don't expect it to disappear completely.
I used mine with an external gps receiver (Sirf III), via bluetooth, and no noticable lag was detetcted during more than 800km (from Bavaria to Paris)...
So, there is something wrong...
I just don't know what....
My next test, will be a clean install of the rom, and drive imediatly after. I wonder if any of the tweaks we apply have any direct or indirect interference with GPS ...
HastaSSSS
I am just saying what I can observe with other devices. I've got Go920 and my friend Go520 and we can both see a noticeable lag, the same with older tomtoms we got in our company. Of course it's much less noticeable than the one in TyTN II or Diamond, when I can clearly see that I've already passed the junction 200m ago and I'm still approaching it in my GPS soft.
I called HTC support Australia and informed them off its fault with GPS lag and its accuracy, I informed them that over 50% of users are having this issue on the XDA forum, they told me that no fault has been logged and there isn't an issue, It may be time to call up the tech support and make some noise to get this issue resolved. its a pain in the arse and it shouldn't be happening.
Maybe we should have a poll to get some hard stats on just how many people are experiencing this problem and add momentum to finding solution.
i just made a 1800 km trip and now i can say that in the city the lag of the GPS make it unusable
Maybe we can try to install igo2006 to see if there is any difference
I haven't had any lag problems at all, the only problem is the time it takes to initially get the satellite data.
Lag time iGO 8
I also experienced the lag time issue. However, it is really lag time as iGO8 seems consistently 20 m behind. Try to stop sufficiently long in an intersection and monitor what happens - my GPS wil slowly count down from about 25 m to about 20 m. In other words its consistently 20 m behind - the lag time is only equvivalent to some 5 m. One thing which seems to improve things is to alter the seting "re-establish lock-to-position" (translation from the Danish menu) and put it at 5 sec. Surely I have not experienced any such issue with my Blaupunkt and Mio A701 systems. And yes it makes it absolutely hopeless in bigger cities if you don't know the road.
I'm aware that there are several posts on this subject and i read almost all and NONE of the fixes and hints helped. It's perhaps my (older) iGO version.
So what version are you running and how bad is your lag?
I run 8.0.044366 (June 24.2008) with a HUGE lag (sometimes even taking me off the road).
I have OCN8 which is basically iGO8. I do not have a lag other than the normal 1 to 2 second one.
I played with OCN on the Tilt but it was SUCH a memory hog that I killed it again. Oh well I guess let's give it a try again on the Fuze. Willing to share your sys.txt?
Try adding:
[msdn]
enabled=0
in sys.txt. Made navigation go from about 2fps to 15fps for me.
and what is it that msdn in iGo8 exactly does?
Am I going to miss something if I disable it?
Thanks and regards,
Its USA only, and its for traffic updates i believe. If you google or wiki it i think it explains it.
@Jiggs1337
I tried it but it still takes me off the road occasionally and the lag ... well takes up to 6 seconds (down from 10) to show 0 (zero) miles after a full stop.
I have the same problem. At low speeds (max 40 km/h) I find the lag less obvious than at high speeds (min 70 km/h). The GPS fix on position however is excellent! Almost on top of the arrow all the time, exacter I think isn't possible, its just the lag of the software, its like it can't keep up with the pace.... Anyone found a solution? Are there any more combinations to try in the sys.txt file to get it processing faster??
I had no time (and will not have any time this year) to either install a TomTom version or upgrade iGO to either OCN or the latest iGO. I do see a relatively good accuracy using google maps and ms live search where the ;ag is mainly driven by the delay loading the map through 3G.
I assume (better I HOPE) that the lag is caused by older software releases due to the fact that iGO ran (was perhaps designed to run) on 200 - 400 MHz devices while Fuze/Diamond and other newer devices run 524 MHz plus. This may (again I hope) be the reason for the lag IF it is truly software related.
We'll see, mid. January I will have time to update but until then I need my phone working and a GPS which at least brings me where I have to go using my common sense as backup "device".
There is no lag with bt gps. Tested it many times.
@kirileman
We all know this but WHY the heck should I carry a BT GPS (and spend some money even if only a few bucks) when my supahdupah phone HAS a GPS chipset?!?! If I would have liked a device requiring an external GPS rcv I'd buy a crappy blueberry, strawberry or whatever berry they are called!
my personal experience, i have a smaller lag with iGO than TomTom..i barely notice it whilst with tomtom i do...
Same here, tomtom has an almost non existent lag (v7.450 com speed set to 38400).
Garmin XT on the other hand is almost unusable. The lag is ridiculous!!.
