From what I've learned on my travels the stock antenna that lives above the interior light cluster is pretty fragile and when people work in that area (replacing windscreens or fitting a dashcam for example) they tend to break then as they don't take any real care.
Have a look in the service menu and see what you get under "GPS Status". If it's...
1. Check Antenna - The antenna has undoubtedly been broken
2. 2D fix - the antenna is receiving a pretty poor signal
3. 3D fix - The antenna is receiving a full, clear signal.
I've had this fixed for a couple of weeks now and driven a fair bit but I only seem to have locked onto 1 satellite despite there supposedly being 12 in view The almanac value is also still a falsy "0", but with all this taken into consideration I'm getting a perfectly good service from the nav itself so I'm not too concerned.
GPS status will be a good starting point. Good luck!

Nav/GPS issues
I suspect mine also has low acquisition of satellites and the system was swamped by the comms / systems of the nearby airport?
My car is currently sorned so it will be a while before I can check using the system you’ve found.

Nav/GPS issues
I just wanted to thank you for this article.
The Navigation in my Z4 just stopped working with the symptoms described (showing me being many miles from where I actually was) and I followed your advice to activate the service menu and saw that the GPS receiver wasn't working.
I located the receiver under the interior light binnacle and after removing, disconnecting and reconnecting it, it sprang into life again !
Great article which helped me a lot
Thanks again.

I’ve tried to get into the service menu but I’ve failed - its probably me just being a bit thick and starting from a wrong menu maybe? I’m doing something wrong!

Push Dial ? Is that press or push it forwards?
3 - clicks right - is that rotate?
