link to a pic? Not sure exactly what peice you are talking about. I have Sirius in my car, has to be run through a FM modulator (also Clarion) into my HU (head unit = cd player, Clarion, but about 3 years old so not compatible directly with Sirius like the new ones). The channel controller (is this what you're referring to?) is mounted to my dash directly above the HU. I had to drill a small hole in the bezel behind it to run the wire through, no biggie. I'll get pics for ya tomorrow, might wanna email me at [email protected] and remind me tho, i forget easily lol.
