Hi everyone. Am a newbie, both here and using a satnav, and this is my first post, so please bear with me.

I have downloaded above map to my Mac, and copied to a MicroSD card. This is what I see is on the card: [Only registered and activated users can see links. ]

When I insert the card into my Zumo 390 (UK Purchased), and go to Settings>Map and Vehicle>My Maps, I can only see the preinstalled UK map as a choice.

If I plug the Zumo into my Mac, both the Garmin, and the MicroSD card show up as two separate drives.

Am I doing something wrong? Or maybe missing something?

Any help or advice much appreciated.

Thanks.
