Remove the aftermarket radio and plug your factory one back in, even if it's just to tune. I had the same problem.

I have a '05 and the tuner doesn't work from the get go. when it was first plugged in, it came up with an error that it can't communicate with the truck. never used and can't be use. WTF. sent back to the factory. still waiting for the factory to fix it.
