Within 2 days of installing my f90bt, there is an annoying problem. When it boots, it shows a message saying "System startup... blah blah" and that message stays there for like 5 minutes. Then the head unit reboots itself and when it's rebooted, it's at the message again. Even though the message is on the top menu, I can still play music. But the system will reboot every 5 minutes or so. I have used avic411 and tried all the methods to fix it. Deleting the gpsxappa or something files, using back up 2.0 files to restore to factory settings, deleting userdata folder, etc. Nothing seems to be working.
What should I do?
Thanks.

 

take it in for warranty

 

Have you tried using the X series flash to make it a 3.0?

I've had no major problems with my F90BT since I put it in several months ago.
