ok guys i did a search and couldnt pinpoint anything about this specifically.

i have the upgraded 7 speaker pioneer audio system and XM,( i assume the factory stereo has a Pioneer XM tuner module) so would an Aftermarket PIONEER head unit(deh-p6800mp) work with the already installed xm tuner?

thanks in advance, i am not the most tech savy guy

and what are your guys thoughts on the pioneer p6800mp???
