    Hi guys, I came across a weird issue with my head unit - a Japanese model Alpine EX9. The HU suddenly lost the settings and did an automatic update, then the issue happened. It rebooted randomly when driving and lost settings after parking for a few hours or a night, then it will stuck in black screen with booting loop. After a few days, it’s hard to boot up and just with black screen and in rebooting loop. Sometimes it’s up, it can run well for as long as I want but when I press the break paddle it will trigger a reboot.

    Any clues where the problem is? The head unit or power supply? Any help is appreciated!

    Are there any pictures of this device?
    Pictures of the connectors that connect the head unit to the car?

    I haven’t taken it out from the car. I will do that if the dealer is no help.
