Hi All!
I'm wondering about this because it says in the owners manual that the 2.5 usb ports are to be used only for charging. So, to do the nav map updates do I just put my usb stick in one of those ports or is there a special one somewhere and I just haven't seen it!
The one to use is the USB port in the dashboard.

I'm in the process of downloading the latest map update to my USB drive. (Wish I had a faster connection, projected time almost 4 hours!) The new map version is 2019.11.
A few weeks ago I updated my portable Garmin unit and it updated to map version 2020.10.
I wonder why the difference?
I suspect there are different maps/numbering schemes for the different units. One reason that I plan to use my Garmin Nuvi for long roadtrips is that the maps are more detailed. I've gone a few places so far with both systems running to compare.
