Beware: I was about to get a new Alpine radio (~$200 installed) when I was informed that it would be about another $130 to get a new harness to accommodate all the extra stuff that's inextricably tied to the radio - even if you don't care about keeping access to OnStar. All to avoid what should cost...

Call me crazy but I think GM should pay for the replacements - including labor- do a recall:1) Car radio buttons were pretty much mastered 50 or more years ago - they usually outlast the cars they're in. Mine also mysteriously went from working fine to spinning without effect after I left it parked ...
