1st of all hi everyone im new a member //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif .Today i unplugged my cars(Opel Astra)battery pole so i can reset the ECU (for some reason)and i forgot that i had the key at the first stage of the key lock and the cd-player Pioneer DEH-P5100R was closed(something like stand-by mode with only some lights on).Anyway when i putted the pole of the battery back on i noticed that i didnt have sound at all...i checked the settings and i now have only bass and i hear a little on the background some things in my songs.Does anyone know what to do?I tried some settings in my cd-player but nothings works i only hear bass of the tracks and all speakers are working so is the amplifier.Maby reset the settings will work but im looking it up on the manual and i cant find the **** thing.
