I have a brand new AVH-4200NEX installed in my 2012 Mazda 6 that is having an issue. Sometimes when I eject the faceplate, the tray that it connects to won't retract to it's upright position. I pop the faceplate off and I can hear it trying to retract but it soon gives up and beeps at me 3 times. If I put the faceplate back on it retracts no problem. Try again and I get the same issue. Hitting the reset button didn't help.
This is the second unit that has had this problem. The first one lasted about 2 weeks before this started happening. I returned it for a new unit which lasted 3 days before the exact same issue returned. It doesn't seem to be getting stuck on the dash kit at all, as any other movement of the faceplate works fine.
I see nothing in the manual about a 3 beep error code and I have only found 2 comments on youtube mentioning the same problem. Does anyone have any insight into what is wrong or know what the 3 beeps are trying to tell me?
