I have the Bose factory radio on my 2007 Pathy with XM/Sirius. I want to swap out my Bose for an aftermarket HU. I'm being told that I'll have to run an antenna for the XM/Sirius even though the HU I'm planning on getting comes with XM/Sirius. Can't I use the existing XM/Sirius antenna to connect to the aftermarket HU?
Thanks for your help.
