1) strange the file GMA in your device/SO (but it's not very important)
2) move/paste del file gmapsupp and gmapprom in your PC
3) test the device with only new map in SD card
4) enable the view of extension for files (better

)

1 - From the files that i select above should delete all except "gmapbmap"(6604kb)?
2 - Where i enable the view of extensions for files?
Thanks

Yes, delete the files listed in my post.
You must have only one gmapsupp.img, so as Roger wrote rename the new one to gmapprom.img
Restart nuvi and test.

2) here the pic (first Spoiler) [Only registered and activated users can see links. ]
uncheck the Hide extensions for known file types

Before i test in the road, just to show you that before i delete the files you say the gps on the info map show this:

rlxu8p

After i delete the files you say only show the 1 one "CN Europe NT 2015.20", the other 2 below disappear

You might try disabling/unchecking all maps other than 'CN Europe NT 2015.20'. Then try testing with just only the CNEUNT 2015.20 mapset enabled/checked, before deleting any file. That's what catymag is referring to when she previously stated that "Nuvi can't support 2 routable maps covering the same area..."
