Garmin Nuvi MapSet format- how to store them in your device

**dwdw** · 4th January 2010, 05:11 PM

Thank You Catymag for the information and the How to!
The more I read the more I get lost! LOL
When I get out I'll pick up a 4gig SD card but how do I format it to be sure its 32 bit? A computer that has 32 bit Win XP I'll use that computer to format the SD card.
Copy and save the 2009 .img
In the Garmin folder of the gps rename it to gmapprom.img Is this the old 2009 map? I copied and saved but haven't deleted it.
In the Garmin folder of the sd card rename it to gmapsupp.img
Thank You --Your the GREATEST!!!!!!

when you format an sd you'll have a menu, choose fat 32-- that's ok for sd

the maps on nuvi devices must be named gmapprom.img, this is the name it recognize as first map.
In the sd just gmapsupp.img is recognized, but put it in a folder Named Garmin and.... just one map per sd

You can only have ONE supp map on your SD card. You can create multiple files with the same name, but u have to create folders for them. When you want to use that particular mapset, then you rename the one in use and copy over the oneyou want to use. It's really stupid of Garmin to have the conventions set up this way, but that's what we have to go by.

Actually things get quite complicated if you wish to merge several maps and you have installed and are running everything from the card.

New 1XX0 series 13X0 14X0 nuvies use different naming convention.
inside system hidden folder, they only support gmapprom.img and gmapprom1.img .
But if you just create new folder named map , you can put ANY.img file inside and it'll work.
By ANY i mean any name numbers letters combination, also it can support a lot of maps i've dropped 10 files inside, and they all worked !! The only positive development in new 1XXX series IMHO

sorry to ask, for nuvi 1XXX series, the "map" folder is create inside the hidden system folder or outside the system folder? i have tried create inside the system folder, but it wont work

Yahoo!! nuvi 1xx0 series, can create a folder "map" in the SD card, then dump in ANY .img and is done, support all maps! so that means can copy all kind of .img maps into SD card!! thanks to cenpac

I have a Nuvi 1470T (Taiwanese version). With the above method I've created a folder "map" on the device AND on the SD card. Then I put a couple of unlocked maps (gmapsupp.img) in those folders. They were both recognised and worked perfectly.
However when I tried replacing those maps with another (gmapprom.img) it didn't work. Do I need to unlock those gmapprom.img files? Or is there another method to install those maps?
