Multiple map files on Garmin 520 plus?
I have a Garmin 520 Plus. I live in California and and heading for a bike trip in Germany and Austria.
I've downloaded OpenStreet maps for those countries.
In the past, due to storage considerations in my old 520 (regular, not plus) I I removed the map I was using to replace it with a map I needed to tavel.
The 520 Plus has lots of storage, so I didn't delete the USA map. I added the Austria map and named it gmapbmap-aus.img and the Germany map gmapbmap-germ.img
It SEEMS like they all load, even though I was given to believe I needed a specific name: "gmapbmap.img" for them to load.
Can anyone confirm or refute that this works? I can't figure out how to be sure until I'm in Germany and I'd sure like to.
Thanks.
