Just bought a 2010 Silverado LT pretty much loaded. Only had the truck a couple days and sometimes the radio works, sometimes not. The radio is on but won't make a sound, and won't let you change channels, it will let you go back and forth to XM and FM, but still no sound. Cut the truck off, and let it sit for a while, crank back and works like it suppose too. Any ideas before I take it back to the dealer.

 

Let the dealer handle it warrenty work
