Hello,
I've recently been having map issues with my Kenwood DNX7230DAB which feature navigation by Garmin. I've updated the devices firmware but the problem persists. As a last resort, I've purchased "City Navigator® Europe NT 2014 Map Update for Kenwood Download" from garmin.com/kenwood. I've paid for the file, downloaded and installed the Garmin Express software and connected an SD card with the device's information on it.
When I launch Garmin Express, it recognises the device, but when I click 'Add Device' nothing happens. I've tried re-launching, re-booting, and re-adding the device's details to the SD card but the problem persists. Is there a method of downloading the maps outside of the Garmin Express software? It just seems an overcomplicated and troublesome way of delivering software.
