I had an aftermarket radio installed at best buy, a couple weeks later, the "cigarette lighter' "accessory socket" were not working any longer. I checked the fuses and had the actual socket piece replaced. The dealership doesn't know the problem so they say. I dont know if anyone else has had this problem. Looking for some advice please

Bring it back to best buy, they screwed something up
