hello and thanks in advance for the help but i got a d3 and installing it in a 04 silverado when i hook up the sirius it does not show up on the menu as being hooked up (the sirius gui button does not light up ). i have exchanged the pnr2 twice and crutchfield sent me a new d3 today and i am getting the same thing. i have 12 volts to the units and i have switched the bus cables around a hundred times. crutchfield has no clue and im running out of patients with this problem. so if you can help i would appreciated it a whole lot . and the BT200 is doing the same thing.

Bad ground or no power on the yellow wire then.
