How can I edit waypoints on a Nuvi 3597

 

I had a 1490 and I could edit POIs & waypoints on the screen.
I transferred my userdata.gpx and current.gpx file to my 3597.
I can add a waypoint but I can't edit the address or the name. I copied the above files to my computer and edited them then copied back and overwrote the ones on the unit. It still shows the same data even though the files have the correct info.
I obviously am not seeing all the files on my Windows computer. I cannot see the system folder as I could on the 1490, and apparently the file that needs to be changed must be there.
How do I edit/change/delete this info????????
