Thread: GPSdaemon:extract the files contained in the GMAPSUPP.img file

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)
... dead links removed ...

Cant modify Garmin NT maps

Catymag said at first post: "You could also extract POI files. "

But I couldn't found how I can do that..... Only *.img files export to other folder.... where are pois?

Can anybody explain to me, how I can export pois from a gmapsupp.img file with that program?

Panoshm read from post #8 to #9 i think you 'll find the answer to your question.

So, we cannot take pois from a gmapsupp.img file...

Thanks, I was aware of expert mode in GPSdaemon and had looked at it some time ago. Unfortunately none of it made sense to me then and not more now when i revisited it. All the stuff about packet data and what to do befuddled me, i have nil programming experience and only basic hex skills. Also the enabling of only 1 - 20 didn't seem to equate to region numbers. I'd not been able to find a guide on how to use GPSdaemon on line so i'd previously abandoned that as probably just beyond me. I just now hooked one of the SP2720's up and tried again with it but the program stalled and i had to kill it in Task Manager, maybe it doesn't like 64 bit OS, i'll try with 32. I'll just keep fiddling around, no need to try helping me here with that, i'll post in the GPSdaemon thread if need too. I'm more used to giving help than asking for it anyway, and also i know the need to build knowledge on what it even does before i ask for assistance. I very much appreciate your input and maybe you'll be able to help me in the other thread eventually.

I'd also read something somewhere about 0x60 command being supported by old devices for dumping regions over USB, and flashing via 0x4B being supported by all units, but again i have no idea how i could use that. I'm hoping that someone would just make a USB dumper, kunix mentioned he can do it but can't really afford the time just now. I'll wait of course but i'm aware that he's extremely busy.
