After reading several posts related to kenwood navigation update I am wondering are there any possibility to update maps on DNX 5220 or 5240 via DVD.
In user manual it is the only option for the map updates. As I have the unit which do not has SD card slot and it's hard to pull out the head unit from the car front panel, updating maps from DVD would be the best option. So is it possible to put unlocked map images into DVD and afterwards update the current maps in the HU.
I own Kenwood DNX 5220 with Garmin City Navigator Europe 2008.
