[QUOTE="Prowler573, post: 1124283, member: 561023"] When you state that the XM's power source is the accessory lead in the radio's harness are you meaning the remote activation output from your HU? More on this later... The noise you've described to us does sound indicative of a poor ground connection so I'd check that and relocate it if necessary. Certainly the noise only appearing while the HU is in aux mode for the outboard tuner would suggest that's the piece of equipment creating your problem. So - check those connections first. If you're powering that XM unit from the remote turn-on in the deck I'd find a new place to get 12v from as well. Most aftermarket HU have a remote circuit output of around .5a or so. I'd wager that SkyFi2 draws more current than that. [/QUOTE]
