radio on max volume all the time !
Afternoon gents, I hope someone might be able to help me sort this out. I fitted an aftermarket radio to my Grand Cherokee no problems worked fine but i've decided to go back to the factory cd changer/navigation unit. However having fitted the factory unit back in the car i cant control the volume - it's on maximum or mute !
Anyone got any idea's as to what's caused this and more importantly how to fix it
