hey guys i have a 05 grand prix and the cd player doesnt work cause it wont take in any cds so today i went to best buy to get a aftermarket one and i found a basic sony one with aux for 60 bucks and i went to get it and i was told installation would cost 180 without the car stereo price included and my jaw dropped the lady told me it is 100 bucks for the wiring harness so i just walked out the store cause im not gonna drop more than a 100 bucks on a cd player. so you guys have any solutions on my problem i was gonna buy the stock radio but i was told it was useless unless i went to the dealer to activate it any ideas?
