Where can I tap into power and gnd for the bluetooth and XM tuner? The leads are not that long, so the options are limited. Can I tap into the factory radio harness for power and find a gnd somewhere? Should the units get constant or acc power? Thanks for your help.

Yeah, you can use the radio's power supply wire(s) to run them. And you can just ground them to a chassis bolt/screw somewhere. IIRC, both those modules have both a constant and a switched power wire, just like your radio does.

Nope...just yellow and blk. So just tap into the yellow on the hu harness and gnd to the chassis? Maybe the IP Bus controls the on/off function? Thanks

Sounds right.

When I had my XM tuner it had the constant and switched power wires, but that was a pretty long time ago. I guess they changed it up.
