Hi Stan,

I've tried that...searched for ages as I'd hoped someone would have put up a pic of water damage etc...but nothing! I'm looking for a pic of the bottom of the board, you can see it when you pull the bottom case off.

Fingers crossed!

James,

I stumbled upon this thread from google, trying to find answers to a BMW MK4 DVD sat nav unit.
Is this the unit you are talking about?
I have one in the boot of my brother in laws car that I was trying to get repaired.
Long story short, I thought the RAM was corrupted as it's behavior indicated as so. Took it to a gentleman to repair who in turn found out the PCB was water damaged.

He advised against repairing it, but it could be done. It is just not knowing what component would fail after being fixed.

Anyway, if you are still looking into this I could get the unit back off my brother in law and take a photo of the board to help answer your question.

Regards,

I
