Hey - just wondering do you need a special modulater to hook up XM or sirius radio? my display has the icons greyed out .. do you just call xm for example and tell them you want to subscribe? or do u need to get something for the AVIC D1 b4 you can hook it up

You need to buy an xm or sirius tuner and install it

I'd probably take it and have it installed somewhere...just to be safe
