No display on screen

If it never picks up the sat signal then you have a defective GPS. Best to just replace it, the repair cost is equal to a new one.

Sounds like you would like to know how to get a radio code because you're locked out of your MMI?
If so, try entering your VIN here and generate your code. If that doesn't work you'll have to take it to the dealer:

you must return you car to the store where you buy the sat nav, for update and revision again. something is missing or bad installing.
God bless you

I bet that rear screen washer lines are broken and fluid damaged electronic under trunk trim.

No solution, same problem, but had many strange moments: 4 months ago during 100 kms or so it stopped, then suddenly came back, and worked ever since. A few days ago, it started happening again: NAV stuck, then radio dead, and gradually the rest disappeared. I did a Reset, and since that moment I see the intro-screen and then it goes black. Hitting the TEL button is somehow also a Reset...

Do the previous 2 posters have anything to report on this matter? It would be VERY welcome!

Thanks,
Jeff
