Not sure if yours has the same problem that mine did, but I smoke in my car and I only use the steering wheel controls.....my sound started going flaky about a year ago and I found that if I "clean the dust" off the knobs on the radio by turning each one back and forth, it corrected the issue.

If for some reason you need a amp, or a head unit, you may want to get in touch with Ed Morad (GTPed@msn.com)
