Connecting the Satellite Radio Receiver (optional)

Before you can listen to XM® satellite radio, you must install the XM® Direct Receiver and
antenna (purchased separately). The XM® Direct Receiver is the central data receiving
equipment required to process the satellite signals from the external antenna. It is typically
installed in the dash, under the seat, or in the trunk or rear of the vehicle. Do not mount the XM®
Direct Receiver near a heater vent or where it can be exposed to extreme temperatures. In
addition, when running the wire for the external antenna do not kink or pinch the antenna cable.
A sharp 90 degree bend or slight "nick" to the outer cable sheath will cause signal degradation.
The wiring diagram will help you identify the proper connections.

Fuses

When replacing a fuse, make sure the new fuse is the correct type and amperage. Using an
incorrect fuse could damage the radio. The MXM4425/G uses one 15 amp fuse located below
the wiring connector: 15 amp fast blow ATO.

Reconnecting the Battery

When wiring is complete, reconnect the battery negative terminal.
