Once you experience XM on a long road trip you will never tune into FM/AM again!

And once you experience the empeg on a long road trip, you'll never tune into XM again...

Haha, you couldn't have said that any better. I beleive they sell little add-on XM tuners that allow you to mount a small display on the dash somewhere, and just run it in through the line in. But, why bother, if you already have an empeg?
