professional Navigation has got lost

I have a 2 week old 328i F30 with Professional Navigation. Yesterday I noticed the map was displaying my position as about 8 kms west of my real position. Up till then it had been working perfectly. I went for a 100km drive south and the position loosely followed me within
a few kms but when I turned to come home it drifted further and further away.

It is now about 120kms south-west of my real position.
Turning the car on/off,
turning on/off guidance
does not fix the problem.

Dealer has no idea, am taking it in ASAP for them to look at it.

Need two things:-

1. Any ideas on how to 'reset' it - This is obviously a software big.
2. Does anyone know if this is a known fault.

Thanks.

The TeleAtlas NAV routing algorithms are a well documented dud here in the US.

Search the F10 Forum for many reports of bad routing / other silly issues in the US. Europe not so bad. First I've seen from your country!

Map updates not reported to help, the problem seems to be with the way BMW has integrated the routing into the NAV.

Thanks for the info, I'll check out the F10 forums...

BTW, this appears worse than bad routing - the system thinks its in a completely different location to what it is.

Took it to the dealer service dept.
They tried reset etc. Could not fix it.
I am taking it in on Jul 3rd...
In the mean time my wife will be lost a lot :-(

Yup, TeleAtlas sucks. It's sad because when iOS6 comes out, Apple is dumping Google Maps and going with TomTom. Guess which company they own? TeleAtlas. There are going to be many pissed iPhone turn-by-turn users.

I honestly don't think the problem lies with Tele-Atlas. Or at least not entirely. I have a TomTom that I've been using for years and It's just as good as any other GPS I've seen. (My maps were updated as of last year.) I truly think the BMW software is mostly to blame.

I wouldn't even say that it's just the software. The maps are also to blame. There's noticeable "holes" in my area, where my cheap $99 Garmin with maps from '09 has some streets that iDrive doesn't. I've essentially just started to use Android Navigation because it's just so much better

I think you are right about the BMW implementation .... but I know that my 2008 535i (Navteq based) NAV worked well ..... problems started with our 2009 328i (TeleAtlas based) NAV and have continued for sure through the 2012 MYs.

Again, that's not necessarily Tele-Atlas fault. My TomTom with Tele-Atlas map that was updated last fall is pretty accurate. One of my biggest gripes with built-in car nav is how out-of-date the maps tend to be. My dad wants to update his 5-6 year old nav in his Passat. VW wants to charge him $300 for a DVD that has 3 year-old maps on it!!! He called the map company directly (I forget if it's Navteq or Tele-Atlas) and was offered the same outdated disk for the same price.

But I can buy a Garmin/TomTom with lifetime maps and get a new map update every 3 months! They use the same map data. So why do the VW/BMW/etc. versions of the maps cost so much and are out of date? Must be because they have to be formatted/adapted for each brand's nav system.

Aside from the Tele-Atlas/Navteq argument. Has anyone seen the actual problem I have:-

The system thinks its over 100kms from where it really is and drifts further everytime I drive
but does not complain about any satellite or system problem.

It could be something as simple as a defective fitting on the gps antennas.

I've seen something similar when first powering up a GPS. The position is off by feet or miles, and then as it acquires additional satellite signals and recalculates, it suddenly jumps to the correct position. I'm not sure why yours isn't correcting.

It's worth noting that the way GPS works is that the GPS receiver gets a timing signal from multiple satellites and compares the clock from each, figures out the offset (delta) and uses this information to compute its location.

If the distance is off, there could be a problem with the GPS antenna, or even a defective clock or other component in the GPS receiver itself.

It could also be fixed by a simple factory reset.... as there could simply be a bizarre software glitch happening.

I have noticed that the 'blue triangle' marking my position has a white circle around it - I am guessing
this means that it cant calculate an accurate position from GPS satellites. So I agree - I think the system is not receiving a GPS signal...
Hopefully I'll find out next Tuesday.

Update:
Dealer has had the car for three days and has not yet been able to find the fault.
They have given us a loaner car until they can find and fix it.
They are working with BMW to find the problem.
I will update when it is resolved.

Hi all

The dealer had the car for 4 business days so it was hard but the fixed it.
They had to replace the CIC and reprogram.

Navigation is just fine now.

Thanks for the update. Was it a Southern hemisphere thing?

I don't think so as it worked for the first two weeks.
I still suspect some sort of software problem but they told me they had to replace the
CIC (the Car Information Computer) whcih implies that the hardware was broken.

Lets hope it stays good :-)

Probably software, but one they can't reprogram at BMW ie. the GPS chipset eeprom..

Anyway, good luck with the new unit, now you will be able to experience everybody elses complaints about teleatlas maps

Most probably your CIC was unable to store the Sat Almanac data either because a defect in its antenna port (no reception) or a defect in its GPS circuitry (reception but no processing). The Almanac is the Sat data that tells the GPS its position.

Thus no software update could fix it, only a hardware replacement.

I have not had an issue with my NAV in the 2011 X5 35d. I did have issues with my 4.8i 2008 where they had to basically change the NAV as it would cut off and on and would get lost as the OP said. I would be 50 miles from where it said i was. I hope I don't have to go thru that hell again, it took two weeks to get this done.

the MB C350 has a very good NAV, very accurate without any holes, anyone know if MB uses Tele-Atlas?
