Thread: Need to update DNX4150BT to latest maps

Hi all

My first post so here goes.

I own an Kenwood DNX4150BT unit with Garmin maps (I presume City Navigator). They are from 2014 and although I bought the unit in 2015 I have never been able to update the maps (using instructions from Kenwood). Apparently you have to now buy the maps from them at $220 which is a big ask for somebody who has retired.

So I downloaded the 2017 City Navigator from a famous site on the Bay but have no idea what to do with them

The SD card I have in my unit has a Garmin folder which contains (see attachment1)

How do I update the files on my Kenwood

Cheers and thanks for any help
