So, here's the gig....I'd like to add my Sony with Sirius and Blutooth AND utilize the FACTORY XM Antenna sitting on my roof.....But, the XM module is on the back right corner??? The antenna cable stops back there?? I was hoping to plug it all in behind the dash? Not sure How I get all the wiring up to the dash? I know the antenna wire isn't that long, I don't think the control wire is either?? I'd really like to avoid the easy way out and just put a little Sirius mag antenna on the roof. BUT, it seems like a ton O work to use that XM antenna..... Any suggestions?????
