Hello. Thinking to play a little bit with my2009 NAVI800 . Want to update software and write custom theme. I know procedure how to do it (haven't tried yet) , but before it i have few questions.

If something goes wrong during flashing from cd and navi will brick, what options I have ?

a) Using MDI and SPS will bring navi800 back to life ?
b) CD with original software will bring navi800 back to life ?
c) Back to life is possible only with bench mcu flashing? If yes, then what mcu is inside and it is possible to download needed files, or need to read from my own radio ?
d) Not possible at all...

I hope these questions and aswers from other members will help DVD800 owners a lot
