Also, tried loading West map into internal 'Garmin' folder and East map on 2GB SD card, but nuvi still only sees West map. No other map choices appear in Settings>Maps>Map Info, only West map.

How do I get both maps to be selectable (I assume) one at a time?

Thank you!

Looking at the garmindevice.xml show there is only 1 option on a SD card gmapsupp ,put the other in to the internal device storage as gmapprom

I guess there is no way to have more than one map in a 'Garmin' folder because Garmin nuvi's like mine can only recognize one map file that must be named 'gmapsupp'.

I tried 'gmapsup1', 'gmapprom', and 'gmapprom1'. None worked, only 'gmapsupp'.

So, it looks like I must have 2 SD cards: one for each map. Please let me know if there is a technique to have 2 different selectable maps on one SD card.
Thank you!

I confirm Nuvì 350 can accept gmapprom.img in internal \Garmin folder, and gmapsupp.img in \Garmin folder on external microSD.
Make sure, when you rename, that you have not assigned a double extension to the File (ie: gmapsupp.img.img)
If you don't see the external Map is likely this matter has happened

It appears the dosyaupload links are dead. All I get is an error page with this:

ERROR: No packages found, please contact the support team. (at least 1 package needs to have the option of 'On Upgrade Page' to 'Yes' with 'Package Type' of 'Paid')

Moderator Note
That would be because there is a later version thread 2021.30
