Advanced Global Technology RVK101 XM Radio Receiver with Car Kit

I bought one of these when they forst hit the market for the size and versatility. The ergonomics make it simple to operate and the built-in RF modulator is more than adequate to pipe XM through your car's FM radio.

I liked mine so much, I purchased a second one for my wife's car.

We remove them from the vehicles periodically and use them on the Harley's while onlong trips.
I would say for Value, Size and Performance -  this is one of the better ones I've seen on the shelves.
