Good day Catymag....

I installed the CN NA NT 2015.20 for test purposes as my daughter is traveling to the USA shortly and wanted to see if it would be useful for her trip.

I first started with an updated version via MapSource (obtained via Garmin update and my faithful NUVI 1450LMT). The IMG could be seen on my phone (S4 Mini) but it wouldn't route.

I then "unlocked" NT folder in PC with Unlock MapSet 2 and saved img to USB and then I "unlocked" image again with gimgunlock (just guessing/playing to see what happened). The resulting IMG I then moved to MAP folder in phone's SD card and using Fake GPS I was able to open it, move around it and search for addresses but it would not route as it would request an internet connection. Once I connected the internet the route and instructions came up.

I also this was odd as I had read Viago would not work with unlocked maps (maybe it has something to do the original MAP was official update?) so it would be interesting if someone else tried it and post their results.
