I just bought an XM Commander radio used. It didn't come with an installation manual. I downloaded the user manual from the XM site but need to see an installation guide. The only thing I'm wondering about is the power wires. There is a red, yellow, and black. I'm assuming black is ground, red is power, and yellow is some sort of remote power on?? If anyone has access to the install manual can you help me out?

Thanks

Yellow is most likely memory, and could maybe go to the yellow wire hooked up on the back of your radio? That is my guess.

If it is remote, splice that bizznatchy into the remote wire off the back of your HU.
