I have a 3592LM since 2013 and have enjoyed using it.

I am wondering how I can transfer/backup the Favourites I have accumulated over the years? I use BaseCamp and Garmin Express on a Mac and both do not recognise the 3592 at all. In fact, the unit when connected identifies itself as a media device and does not show up on the Mac desktop at all, unlike my other Nuvi devices.

The 3592 is connected to the Mac via the usual USB cable I use for my Nuvi units and direct to the Mac, not through a hub.

Can someone help please?

Thanks!
