I recently received a Garmin Nuvi 2460 GPS, and it works as designed.

A few days ago, I installed the Garmin Communicator Plugin v4.0.1. When I did so, I got the confirmation notice that the plugin installation was successful.

But when trying to access MyDashboard, via the Garmin website, I get an alert: “PluginNotInstalledException”. Yet, I have verified that the Garmin v4.0.1 plugin is in fact resident in my Library/Internet PlugIns folder.

So I called Garmin, and they did give it a valiant two-hour effort, reinstalls, trying FF and Chrome, etc., but still no joy. It was quite clear that their Mac expertise is seriously lacking. The call concluded with their suggesting I wait for the next plugin version.

Something, me thinks, is precluding the plugin from launching/running, but I do not know where to look (logs?) even if such analysis is possible.

How do I get this plugin to work as designed?
All suggestions most welcome.
