Android Auto no longer working

use the function in Syn3 Updater under the utility tab to do this

Again use the function in Syn3 Updater

I doubt any of this will fix your AA though

Again, thank you for your help. I’ll delete my account at this point as there seems to be no way to correct my Sync unit. Thanks to everyone for your input.

OK, it doesn’t seem like you really want to try either, buy a replacement APIM.
