Hello Eddie
The Newest version (MK3) we sell for US$545.00
It includes all that you require for a successful installation. Maps and software are preloaded on an SD Card.
The only 2 things that you may want to consider are a rearview camera or an ATSC TV receiver to receive digital TV channels.
We have both of those available for purchase and shipping with your unit should you wish them. Let me know, and I can send further details.
Best regards and hope that we can be of service.
Joe
