I have a this model and I'm curious if I remove my factory head unit and install the AVIC-N2 will the XM that's paid for a year still work? The unit has a XM interface but I'm assuming the free yr service would be voided? Any thoughts before I install? I'm probably going to go ahead and install the navi system and just purchase the XM but if its free for a year I can throw my Magellan mobile Navi in til the year is up..

Any thoughts much appreciated.
