How to install multiple maps on Garmin the easy way

**vesgo** · 1st November 2009, 12:22 PM

ok, i think i understand everything in the posts, but theres something im not sure though!
I can put both maps in my gps but i can only select and deselect one!
I'll explain:
I've the new CN Europe 2010.20 from mapsourse unlocked in my gps with the unl files. Everything works fine.
Now i got topolusitania v.0.80 (portugal), that its a non routable map and i would like to put it together, so i tryed everything in the forum, i tried to put both in the internal memory, tried one in the internal and other in the SD card, changed the names, tried gmapbase and gmaprom, gmapsup, gmapsup2, etc...
I would like to know if it's really possible to get both maps selectable and unselectable in the Settings\map\map info?
If it is whats the best combinationof files in the GPS\SD Card?
Help apreciated!
THx in advance!

You have CN Europe 2010.20 in internal memory and it works fine-ok leave it there like it is.
download this topo lusitania unlocked IMG

put it in your sd in a folder named Garmin
that's all

Hi,
does the multiple gmapsup2.img, gmapsup3.img etc works on the Edge 705?
I only managed to install one gmapsupp.image in the 705 and one gmapsupp.img
in the SD card.
Not managed to see the gmapsup2.img.
Any hints? Tricks?
I have the correct unlock files BTW.
Tks, pippo

I mean the old nuvi 350/370 series... the very first models...

Just tried this on my old nuvi 370.

The 4th & 5th map:
4) rename map4.img to gmapsup2.img and place in Garmin folder. Repeat the process to unlock the map, and name gmapsup2.unl

5) rename map5.img to gmapsupp.img and place in Garmin/App/ folder. Repeat the process to unlock the code, and name gmapsupp.unl and place in Garmin/App folder. This last map doesn't always work though.

does not work!
Anybody experienced success with Nuvi 350/370s?
If so, what firmware version?

Hi,

Nuvi's have problems with multiple maps, only one map per device (one in device and one in SD)

Try to merge them with this tool

Put all unlock codes in one .unl file (no gap between: 1 code - 25 chars, 2 codes - 50 chars, ...) per device, named as .img file
