Can we just then save back the extracted file to the Garmin folder? No need to generate a UNL file again?
GPSdaemon:extract the files contained in the GMAPSUPP.img file
GPSdaemon is in english , it lets you connect to a GPS handheld over USB or serial com port. It should get the unit ID and extract the files contained in the GMAPSUPP.img file stored in the GPS and save them to a folder of your choice.
You can also extract files from as GMAPSUPP.IMG file on PC or card. First you create a Map List, then select one or all files and start Map Extract. The original files will then be recreated in the folder you've chosen.
You could also extract POI files. See post n18
By opening a DOSwindow and giving the command "gpsdaemon.exe -e" you will enter Expert Level which allows you to send Hex data to the GPS over serial or USb. You can also set some parameters as well as packet headers.
Addionally, there is 'Full model': [gpsdaemon.exe -full] which enables dumping of regions. See post n 22> for info.

Can I transfer POI from one img to another img?
Extracting POIs... Mmmm! Interesting.
1- Which file contains the POIs? .TYP? .MD2?
2- If one of those, I guess they are encrypted. Sounds like a challenge for me...
Edit:
3- Why do I get a "Cannot open USB port" with my 3750? Do I need a service cable or do I need to put the GPS in a special mode?

@ Turbo
-> 3- Why do I get a "Cannot open USB port" with my 3750? Do I need a service cable or do I need to put the GPS in a special mode?
This function is for older garmin devices that support garmin protocol for communication like etrex, gpsmap etc. where POIs and maps are stored in a non-accessible part in the memory.
BTW maybe you will be interested what I have wrote here:
Code:Please Login or Register to see the links
In GPSdaemon gui photo at first post I can see 2 columns named "product name" and "area".
How can I change "product name" and "area" information in an img file in order to see it in GPSdaemon ?
These data shown in those columns are data from the img loaded in GPSdaemon. I dont understand what do you mean exactly

I want to change these values.
Lets say that the original map is the one below.
... dead links removed ...
I split the map with gmaptool.
Lets say that I want to change "product name" to "13" and "area" to "14" in the first map on the mapset. What program should I use ?
After that, if I join the mapset with gmaptool, and when load it in GPSdaemon I should see the changed "product name" and "area" values (see below)
