Can anyone help?
Have downloaded to my Mac from post No64 this thread City Navigator Thailand NT 2013.30 for my Zumo 390.

From downloaded File, Thailand 2013.30>IMG>Unlocked IMG, I took "dual version" and put in a folder "Garmin"on SDcard.

On Zumo...Settings>Maps & Vehicles>My Maps, I can see the map. See photo:
[Only registered and activated users can see links. ]

However, when I try to do a test run, it only shows the preinstalled UK map.

If I connect GPS to my Mac, I can see the Thai map in Base camp.

Have I missed something out?

Zumo 390

Software 3.60
