X920 Bt resets channel and equalizer settings

[Neo Anderson]

Hello,

I have a pioneer X920 bt installed on 2007 bmw 335i coupe. I have been facing this problem. When I tune my FM channels and change my equalizer settings, the configuration remains as long as the car is on and after about an hour I shut off the power. When I turn it on again, all the config is gone. I replaced my head unit, but I face the same problem. In the stock unit with BMW 335i I didn't face this problem. Any ideas? Is there something specific I should be looking for?

 

Thank you for your help.

Get it installed properly.

Smith & Wesson doesn't make someone smart. Can someone with a little more braincells reply? I got my installation checked by two installers who are considered to be experts at doing this, but since they could not resolve it. This being a forum of experts from everywhere, I would appreciate to get some ideas that can logically point me to where the problem could be.

 

Thank you.

Well take it to another expert and have it looked at again. Any installer should be able to find the obvious problem. And if it isn't obvious, then your unit is likely defective and will need to be replaced.

Sounds pretty simple, actually. The constant battery power isn't connecting. Did you get the proper wiring harness? They are each a bit different by brand and have directions that work like a learning tree. The right harness saves time and frustration.
