Map update & Gps?

[fredgroves]

BTW, I do see funnies from time to time.. eg yesterday, driving down the M1, suddenly I look down to see it telling me about the UK speed limits - it only does that when you are not on a UK road, then join one.... which means for a little while it thought I was in a field or something.

I've had OEM sat nav in my cars for about 10 years now. I have to say that this one is the most disappointing unit I've had.

I'm a business user and its the one thing that makes my GTD a less than optimal company car...

Is it always the same place you see this happen??

Hi Fred,

No completely random, this morning I was way off course for 20 secs or more with the wrong voice instructions as well, then back on course.  Its like a loss of gps lock but the screen still says 9/12 sats so I presume this means locked?  VCDS shows the same data. 

Hopefully it will do the same on the way home & I can cross reference the lat & long with my iphone gps app

Yes I totally agree both systems in my previous cars were dvd based (BMW & MERC) & I never had this issue as frequent as this.  I need to revert back to the previous maps to see if this is purely a map bug issue, unfortunately I have been unable to source the older map data (2014) & my dealer can only order the new update on sd card   I really need someone who has the 2014 maps on an SD card in drawer somewhere that I can borrow

Why are you bothering with the dealer when you can download the nav pro maps yourself?? Also you'll find that systems using a dvd based system are exactly the same as the VW one in fact the vw one will be quicker. I've had no issues at all with my nav pro and its far from disappointing.

You mis-read my post I have already downloaded and install the latest maps, however I wish to revert back to the earlier 2014 map data to see if this helps.  The older map data is not available online or via a dealer.

I can't see putting a previous map on helping to be honest. Have you tried re downloading the latest ones again and updating again. Maybe you've had a glitch when downloading? May be worth a try.

Depends if the new update is bugged?  I will re-download and re-install but I am sure that if there had been a problem last time the car would of failed to update.  I use the exfat format on the sd card as that seems to be the best

When you do the update, it contains a checksum for the map data.

If the download was corrupt, the car would tell you...

Its 100% not that.

I still think its either to do with interference or inaccurate map data. Either is possible.

Yep I agree had a little off road issue on the way home but both the pro nav gps and iPhone gps showed the same coordinates so it's not a gps issue.  However the map showed me crossing a field for 10 secs before jumping back on track.  All very strange and random

My sat nav told me yesterday to turn left onto "Stuttgarter Strasse". You might not think that is weird.... except I was in Cardiff city centre... will show this to my dealer next time and see if it makes them laugh.
