New here. Just upgraded to an 04 Silverado ex cab Z71 (from a 91 F250). Always looking for new ideas. 1st mod to the truck was replacing the factory radio (it wouldn't take CDs). I installed a Sony CD player and a Scoche Radio Interface Adapter. I have had Chevys before, although I am not really sure what possessed me to get the Ford. Glad to be back in a Chevy.
