I have a good working Pioneer AVIC-N3 for sale. Unit is near flawless. Comes with everything to install it and a remote to control it. Has the navigation DVD also.
Unit has already been bypassed to watch video while driving.
Also I will include the ipod interface that was an additional $50.
For an extra $25 I will include the XM radio add-on module, antenna and IP-bus cable.
If you buy everything I will include a 6-Disc changer with all the cables for free.
All the details for the radio can be found here.
