Hello,

First time for me posting here. I recently bought the thew C Class 220 with AMG line. Everything was good until last week.
All command / audio 20 system is not running at all. The screen only displays "bootloader active".
I've checked fuses, tried several options:
restart the system several times (pushing on/off button for 20 seconds...),
disconnect the battery for 5 minute,
look at the hidden menu

But no effects, the screen only says "bootloader active".
==>no radio, no phone, no nav, no air conditionner control, no time setting.........





Dealer has no solution except doing a full diag, but I do not have time wasting half a day at the dealer's garage.

any suggestion ?

Did you try pressing/holding the CD Eject button for 10 seconds?

Yes, but no effects, I've tried it in each key positions...
Thanks for your reply

Not a solution, really, but don't spend half a day at the dealer... arrange for a loaner and leave him there with the car

Do you have Comand (note one M) OR Audio 20? Audio 20 has 7" screen and nav (if any) from a Garmin SD chip. Comand has an 8.4" screen. Sorry I can't be helpful, but I (and others) would still like to know if your problem might someday apply to me (us).

Hello,
I have an Audio 20 system.
I will let you know how this issue has been solved (if I can catch a dealer...)

This should have been resolved by now. So, what was the fix?

In addition, question is if we can flash audio 20 firmwares using software version on usb stick. I heard for certain brands this can be achieved by end user.
