RV owners know that nothing's better than satellite radio on a long road trip. Keep your XM Onyx radio secure and accessible in your RV with this wall plate. It connects the Onyx to your Concertone DVD receiver, and keeps it charged. The Onyx is not included.

The ZW125 wall plate features a push-to-lock-and-release cradle that holds your Onyx and allows access to its controls. Mount the plate to a 12-volt power supply, then run an audio cable from the plate to your Concertone DVD receiver. Warranty: 1 year.
