Setting up the GXM 30A is fast 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 unit. Then choose the XM subscription that best fits your needs to start receiving XM satellite services.
The type of information GXM 30A provides to your unit depends on your subscription package. With a subscription to XM WX Weather?, portable marine and aviation products display detailed weather, including NEXRAD radar. You can also add XM Satellite Radio to these units for non-stop commercial-free programming.
