Remember the XM SkyDock? It’s now available for purchase for $120. For that price it will give you full touchscreen control along with tagging capabilities over your in-car satellite radio. SkyDock features a built-in XM tuner and PowerConnect FM transmitter and will plug right into the cigarette lighter / power adapter socket where it will also charge your Apple device.

XM is making the App a free download from Apple’s App Store, but you’ll still have to run the antenna cable along the inside of your vehicle’s weather stripping to attach the magnetic antenna to your car’s roof (just above your front windshield) for optimal results.

That could get messy for some people.
