I am having a problem of my XM presets not being remembered. AM FM ones are OK, and the Stock ticker functions work, but the XM picks are lost between drives.

I am able to hold down for 2 seconds and store presets, but they are lost when I turn off the power. I am receiving stations 7 and 175.

Any ideas?

Check the power connections on the xm tuner. Yellow to constant and black to ground. Sounds like one of them either has a bad connection or the yellow is hooked up to accessory.

if the constant power is hooked up to a cigarette lighter, some cars shut power off to those accessories after a while. even though it is a constant feed
