Hey Everyone,

I have a Dice Ipod/HD installed in my '02 X5 and love it. So far so good, I also purchased a panavise mount and installed a Sirius Audiovox PNP-3. The orange color of the display at night matches the radio and is a much cheaper alternative then the 700 I would have to spend to get my radio up to spec for an OEM install.

I do have an issue however, currently using the AUX In, because the PNP-3 is a cig-lighter powered device, I have bad engine whine. I imagine this is because of a ground loop issue because of feeding radio from different power sources. I have been using a ground loop isolater, but the sound is muddy and low frequencies are gone.

I am thinking of trying to fix this with cutting off the cig-ligher power supply and soldering the power and ground to the common power source of the radio.

Questions: Should I run the power to the sat radio to one of the pins on the back of the radio to prevent noise, or should it go to the dice power source to prevent noise?

Additionally where can I tap into switched power so the radio comes on and off with the car going on and off (or in ACC mode)

Any assistance would be greatly appreciated!

Best,

-B
