Garmin GXM 30 in very good condition, spent its life inside the fairing so it has no sun damage. I've been holding on to this antenna thinking I may go back to XM but decided its time to let it go. For anyone that has priced one of these used, you know how much the pricing jumps around. So I'm going to start off with asking for $70 OBO. For more info email wikd@att.net

The compact, all-in-one GXM 30 delivers XM satellite weather, traffic, and radio to your compatible Garmin GPS navigator. With the GXM 30 and a subscription to one of XM's satellite services, you can check the weather, avoid traffic backups, or listen to commercial-free radio while driving with your navigator in tow. Setting up the GXM 30 is quick and easy: simply position the antenna where it has a clear view of the sky and connect it directly to the USB port on your GPS receiver.
