I'd love to have someone explain how to reinstall old version of avic f320bt.
I am asking because I've got avic f320bt version 1 000000
I updated my Bluetooth version to 3.3 and it seems it is not compatible or I didn't do it as it should. First I copied the 3 files in the update fomder to an sd card, inserted it and turned on the car. It booted and asked me if I wanted to update. Now when I turn on telephone mode, there is only searching ... which doesn't detect anything. Can I downgrade to earlier version. If yes where can I get it and how do I procede?Thanks a million for the help.
