Unable to download purchased map

I just purchased an eTrex Touch 35 for hiking in the U.A.E. but discovered the worldwide base map contains little more than an outline of the coast in this part of the world.

There are no topological maps available from Garmin for the U.A.E. so I reluctantly purchased Garmin nüMaps Onetime City Navigator Middle East & Northern Africa NT so I at least have a few features to help navigate.

Since there is no Garmin linux software available, I switched to Windows 10 and tried to install the Garmin Communicator plugin for the Waterfox (64-bit Firefox) browser, but the plugin gets stuck in an endless loop after installation where it re-starts Waterfox and then proposes installing itself again. The Garmin Communicator plugin does not support Microsoft Edge (the default Windows 10 browser).

I finally tried using a Mac Mini and succeeded to install the Garmin Communicator plugin in the Safari browser. When I tried to download the map I had purchased, I was asked to install Garmin Express, which I did, but it did not download and install the map (and did not give any error messages).

The map I purchased has disappeared from MyGarmin so I'm stuck.

[email][email protected][/email] has not replied to an email on the subject and does not supply a telephone number.

For the US$89.99 I paid (for a map I don't really want), I would have expected linux software and, failing that, Mac and Windows software that actually works.

Any help with downloading the map I bought would be much appreciated.
