Working out the gremlins in the 07 Sierra I bought a while ago, sometimes I turn up the volume using the steering wheel buttons and the radio goes into 'scan mode', when I turn it off and power it up again most times it resumes scanning.
Is there a chronic problem with the steering wheel buttons? Is there an easy fix for this?
After this one I'll look at changing the back speakers, 1 is dead, other barely makes any sound at all.
Thx
