Warren_G Posted February 15, 2013 Report Share Posted February 15, 2013 Your XM module is connected to an ignition switched power source, I believe it needs a constant power source to maintain memory. The yellow wire (one of only 2) in the harness should always be powered. Quote Link to post Share on other sites
