I found this discussion

SYNC 3 Software and Upgrading Screen Hardware

Hey, don’t worry, it’s recoverable. Having to change some asbuilt is not unexpected, and may or may bot be required depending on some variables. That’s why I asked if you had one. Since now you need it, it won’t be money spent without reason. I assume the APIM is actually operational , for instance radio or other functions, right?. If so, if you do not want to to wait until getting the new adapter, you may try reverting the changes… I will review the log later once I’m back at home.

Sounds similar
