Why does the head unit lose the audio control settings everytime I turn it off?
I always have to readjust the Bass and Tremble. Does it happen to any of you?
And if somebody have this same problem, How can it be fixed?

 

OEM head unit? Sounds like a problem that should be taken care of under warranty.

 

You could also be having a grounding issue... I think my stock radio was having the same problem, but I did a DD kit and swapped out the deck.

Give us some more info on your system so we can diagnose it for you!! (stock or modded)

 

It's a stock radio, but I dunno what's going on with it.
When I turn the car on I always have to readjust the audio bass and treble.
