I recently purchased a 2013 MDX basic. Is it possible to add the factory navigation system to the vehicle. I have seen that I can get the radio unit with navigation and the display monitor for the dashboard. I know that I will have to aquire the dashboard panels for the monitor install. Anyone know if this is possible and if I need other additional comments or is this a plug and play situation. The current radio is the 6 disc changer with SiriusXM.
