Hi All,

Very recently started having an issue with the BMW Sat Nav in my e46 M3. it's a MkIV - version 4 1/9.

I've read many posts with interest (tried some of the hint n tips to no avail.) Basically a few weeks ago the map went "crazy" and shot off about 50 miles north of my location - and yes the GPS logo disappeared from the top right hand corner. Magnetic north was all showing fine.

I left it for a day and it started working again fine for another week. Then today it did the same thing although this time it dropped from 6-7 satellites visible to 1 or 2 then nothing. Now "north" is way off (more like south meaning the map now thinks I am in France!). I reran the software update disc I have but this has not solved the issue. In the "Engineer" menus it's not picking up any satellites now, almanac is yes, and GPS status is "Satellite Search".

I guess the next thing to try is removing the battery for 15 mins (as per other advice in this forum?). Additionally I'd like to check out the GPS antenna/receiver connections but am not 100% clear where this is located on my car? Is there a bit in the stack (where the Nav DVD unit is) and also something near to the Harmon Kardon "Sub" on the rear shelf? Any pictures/advice would be greatly appreciated!

I've had the car about a year and until last week all was good!

Thanks all in advance,

Darren
