Ok. I am able to get my dead MK3 power on again. It can read CD I inserted in.
However I am still not able to upgrade or downgrade NAV OS using various CD media. The screen still showed blue blank screen. I will instead buy a factory Cd as you suggested.

Question. Should I buy BMW Mode 2 Form 1 'blank" CD? Should I buy this fcatory CD - V32 P/N 01 59 0 141 891 directly? I was not clear on the suggestion. Where to buy? I asked my local BMW dealers. They did not even carry it anymore. They need to get it from East Coast somewhere. I think BMW NC plant?

Anyway thanks for your suggestion.

Get the Ver.32 P/N from the dealer or from an online place such as getbmwparts.com. It will be in Mode2Form1 from the factory.
