My son bought me an XM Satellite Radio with Boom Box 3 years ago for Christmas. We love it. I have the boombox at home, but when we go away, we take the unit with us and play it camping, in a cabin, anywhere really, and always get reception (unless it rains sometimes).
We bought the unit that fits the truck and just transfer the face from the boom box to the truck for the ride, then back to the boombox when we get there.
Hope this helps.
