I got the unlock code and unlocked my stereo, after the battery change, but now it goes up at it's loudest just by touching it, or if it runs over a bump , it's just up to the highest, or you have to keep turning it for a long time to get it down, and by then I am deaf, it's a 1997 Monte Carlo, and the place I got it tuned up and a new battery, put it on loc, so I had to pay for the question and the unlock code, and now the thing won't play normal, can you please help me. Thanks so much.
Optional Information:
1997 Chevrolet Monte Carlo
Already Tried:
