Audiovox XM radio turns on and then gives message that antenna connection is at fault and then shuts down. All antenna connections direct to radio are ok.LC 24171-209, 1WU5Q083
I had a similar problem with a portable XM radio. The antenna, connection and cableall looked fine, however, the centre conductor of the antenna lead was damaged where the lead went through the door jamb. Look for any type of crimp in the antenna cable and if so, either get someone to repair the lead, or get a replacement antenna.
To receive XM weather or audio, the GPSMAP 740s requires a GXM 40 Smart Antenna with XM subscription.
The GXM 40 Smart Antenna (010-00730-00) is used to receive weather and audio service from XM satellite radio. For details on XM services please visit our XM webpage.
Once a GXM 40 Smart Antenna has been connected to the GPSMAP 640, the device can display the subscription information for the antenna.
