MAP "CN europe" for KENWOOD DNX5220

Another solution which I have never tried and dont know if it would work would be to open up the Kenwood unit and see if it has an internal SD card. Many Kenwood DNX units run the Garmin navigation off of an internal SD card. I dont know if the DNX5220BT functions that way but if it does have an internal SD card, it may be better to swap out the card with a larger SD card that could handle the full map. After that whenever you need to update the map you could do it through the micro SD connector and update the full map. Again this is all just speculation as I dont know if the DNX5220BT has an internal SD card but it may be worth a look.
