Hello catymag,

My device can use the NT type map products, the original Quest cannot. Here was a confirmation response I received from GPS City tech support.

Dear Sir:

Thank you for your interest in GPSCity.

The Garmin Quest 2 is a discontinued device and has very limited memory.

Smaller regions of the City Navigator maps can be installed using the Garmin City Navigator North America NT DVD.

We would highly recommended upgrading to a new GPS.

I have a gmapprom.img file that I don't know how to take smaller sections from and upload to the Quest 2? Also, I have installed Mapsource and have City Navigator North America NT 2016.1 Mapsource can communicate with the Quest 2 and I transferred waypoints and tracks that are in the Quest 2 memory.

I was able to unlock the mapset using Unlock_Mapset_2 but now if I go to the map and select a section of the map I receive an error telling me to reinstall the mapsource again and that it could not open an index file CNNANT_2016_10.mdx - I checked and this file is not present?
