Upgrading my head unit so I'm selling the old one. I have an 07 with monsoon system. The nav is is great shape, I'm pretty sure my new one comes with an antenna so this will come with the unit, nav cd and antenna. $500 shipped!!

 

Try ebay too, mine sold pretty quick on there for exactly what you're asking for yours.

 

Do you still have the unit for sale? I have a 2006 with 6 CD, Monsoon with XM, but I don't know if it is a direct fit. I've been searching the links looking for an answer.
