i have an 04 honda accord with factory XM built into the head. Can I use the XM tuner with my d3 somehow? I hate to spend the cash on an xm tuner since I already have one built in.

And if I cant, use the xm tuner off the factory head, can I at least use the factory antenna?

Any help would be appreciated.

No you can't use the factory tuner, gotta buy the Pioneer one

can i still use the factory xm antenna though somehow?

YOU MAY NEED TO REMOVE A PLASTIC PIECE THAT SURROUNDS TEH ANTENNA PLUG BUT ITLL WORK FINE ONCE IT FITS
