How to install multiple maps on Garmin the easy way
[[hide]B]1) name the map1.img to gmapbmap.img and place in Garmin folder
(this is usually the World Base map and is usually not routable)
2) rename map2.img to gmapprom.img and place into Garmin folder. Use the JetMouse keygen (you'll need the mapID no.) to generate the map unlock code. Copy the code and paste into a text file, and name it gmapprom.unl, and place in Garmin folder.
3) rename map3.img to gmapsupp.img and place in Garmin folder. Repeat the process to generate unlock code for the map and name gmapsupp.unl.
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.
You can check that everything is working by opening GarminXT>Tools>Manage Maps....all maps should be showing.
you can also use the Garmin unlocker program to unlock all you maps on the computer first, then rename and transferring to Garmin folder on your device
OR NEW METHOD:
You can put all the unl codes in one .unl file
NO gaps or . , etc just put one code in then the next straight after it
One gmapsupp.unl is enough
(Thanks Thefatboy)
note :
in nuvi 1xx0 series and newer (37xx 34xx etc), you can create a folder "Map" in the SD card, then dump in ANYNAME.img and is done, it support all maps[/hide]

Hi, unless you have made a typo in your message here, it could be because you haven't named the unl file same as the map file gMApsup2.img + gAMpsup2.unl (capital letters done by me to highlight).
Don't know if it's just a typo in the post - if it's like this on your device, for sure it won't work. It needs to be exactly the same name.
Good luck and best regards!

Multiple maps on nuvi 2xx
I don't think gmapsup2 works in the nuvi 2xx models, nor does the garmin/app folder idea. But you can use gmapprom1.img and gmapoem.mg in the garmin folder, with the slight annoyance that you can't deselect gmapoem.img via [Wrench icon]/Settings/Map(on second screen)/Map Info So you can have gmapbmap.img, gmapoem.img, gmapprom.img, gmapprom1.img, and gmapsupp.img in the garmin folder of a nuvi 2xx, and also a different gmapsupp.img in the garmin folder of an SD card (and then you can swap in and out as many SD cards as you like).
