Morning everyone, I've replaced my two door speakers yesterday with 2.5" Sony Xplode speakers and today I will replace the two in the extended doors. Now im looking to replace my head unit in my Silverado. I was looking at the 6 disc factory unit (mine is only one) but I know I will not have the best audio possible. Problem is I am looking to this summer to replace my steering wheel with one with the controls built in. I don't need to have gps nav or a computer for a radio. If I went aftermarket it would be just a cd changer with a usb port for my ipod. Any advice would be appreciated.
