Just purchased my 2014 Mazda 6 Touring 2 days ago. So far, I think the car is great. I would like to find out how to add Sirius to my car in the most aesthetic way possible. Does the grand touring really offer a totally different receiver or is there a way to modify what I have to have the same capabilities as the grand touring? I already have a subscription to Sirius and was using a an external receiver with an fm modulator on my previous vehicle. I was just hoping to keep the Sirius but have it look "cleaner." Any help would be appreciated.
