I use a Sirius radio but it's not connected directly to the radio so I'm always changing stations and am freezing my *** off because turning the fan up on the heater creates static also. Every truck I see seems to have a satellite radio so it must not be as expensive as I've been quoted to get it wired to the radio. It's an '07 Kenworth and the dash looks impossible to take off. How much will it cost me to get a nice new Sirius radio professionally installed and end my insanity? Thanks.
