dnaber Posted May 21, 2019 Report Share Posted May 21, 2019 I updated my AVIC-7200NEX about a month ago and it has given me nothing but trouble since. It screen freezes on startup, it's GPS is about 4 MPH slow, and I keep getting a ODBC connection message. I would like to down grade the firmware but not sure where to locate the the old firmware file. Any suggestions? And before anyone asks, I have tried reinstalling it twice.
