How to get two separate map files on SD working on some older nüvi GPS models

**smokefree** · 26th January 2013, 05:02 PM

In 2012, Garmin has provided updated firmware for older nüvi models to allow for a second separate map file on an SD. For instance the nüvi 250 here:

I have tried to put two maps on an SD but had a problem figuring out the right syntax. Tried following combinations before eventually being successful:

- 1st map gmapsupp.img in folder \Garmin -- 2nd map gmapprom.img in folder \Garmin: only 1st map recognised
- 1st map gmapsupp.img in folder \Garmin -- 2nd map gmapprom.img in folder \Map: only 1st map recognised
- 1st map gmapsupp.img in folder \Garmin -- 2nd map gmapsupp1.img in folder \Garmin: only 1st map recognised
- 1st map gmapsupp.img in folder \Map -- 2nd map gmapsupp1.img in folder \Map: no map recognised
- 1st map gmapsupp.img in folder \Garmin -- 2nd map gmapsup1.img in folder \Garmin: both maps recognised

Tried only on nüvi 250, but should be fine on following models: 200, 250, 260, 270, 200W, 250W, 2x5, 2x5W, 7xx and 7x5. Just make sure you've updated to the latest firmware version.

Enjoy!

Mod Edit: gmapsup1.img works as 2nd map in Garmin folder on SD card also in 465T as well as all 2xx/W & 7xx series models with recent US/EU fw only. Not applicable to Asian fw models.

In all the above-mentioned units, internal detail maps naming convention is: gmapprom.img; gmapprom1.img; gmapsupp.img and possibly gmapoem.img (gmapoem naming may not work with all maps, will not be de-selectable even if it does appear in map info).

Maps must be placed in Garmin folder only on both unit and SD card observing naming as above. Other file names or placement won't work and nor will 'Map' folder work in SD or internal memory with the above series models.

In all old nuvi work gmapsupp.img and gmapsup1.img from Garmin folder in SD

If you read on Noeman i think somewhere on map or in FW update theme you will see that name for nuvi

You can also find this in nuvi FW.

Not all old nüvi models! Nüvi 3xx and 6xx for instance do not recognize two maps this way on one SD card.
Not sure about nüvi 5xx models, but odds are that those are not suitable either. See here:

There is no updated software for nüvi 5xx with two separate map files on SD now. This model is not popular...

Nuvi 3xx, 6xx and 5xx ar super old

I write Garmin to add support for two maps from SD for 3xx,6xx and they write back that this nuvi will also recive update for two map's, but they can't tell when will be update available.

Hi to all of you, I'm a newbie, or frankly said just an illiterate in GPS stuffs

:-). I've got one question: Does all written above applies to my old Garmine Etrex Vista HCx with SD 1 GB- software version 3,20 and GPS software version 2,80 to <How to get two separate map files on SD working on some older nüvi GPS models> and to be more specific, I like to install from VRU002R the Bulgarian Black Sea Coast slice only, abt 1,81 MB. For now I have only BG Topo Lat 13.12 installed on device and abt 600MB free space. Tried to install on device by using Mapsource but result was a disaster: None installed,Bg Top Lat deleted. I read somewhere in bulgarian forums vague and controversial posts that it's possible using GMapTool, that this Blue Chart format is discontinued/ inapplicable for my device and so and so for...If anyone help me with technuque on how to procede, if possible I'll appreciate very much. Thanks in advance

eTrex Vista HCx doesn't support g2 Vision charts, you must look for HXRU002R (g2)
[Only registered and activated users can see links. ]
There is a limit of 2GB for a single map. I suggest to keep Bg map (gmapprom.img) in internal memory and the chart in sd in a Garmin folder named gmapsupp.img
Edit: 2gb limit is gone with sw 3.00

Caty! No problem with g2 Vision charts too. I do not have not-g2 Vision version for my region and so I use g2 Vision!

Device ignore 3d, aerial and auto guidance simply! Only one moment that g2 Vision is more expensive

This unit have the same small problem with both format with not-g2 Vision so as to g2 Vision in map control menu. It is not significant but the best way delete some sub-maps. We discussed that in one of old thread...

Ok, thanks, I don't remember, I simply looked at product page and Vision are not listed.
