Thread: Need help with Street Pilot 2720

Then the faulty map is probably 'gmapprom.img' if it was loaded with MapUpdater. I don't no how to recover such an old unit, my experience is with newer units which can flash a cure fw so they can enter MSM. If it could be seen by WebUpdater then it would have been easy to just load the map again with a good image: [Only registered and activated users can see links. ] and [Only registered and activated users can see links. ].

It seems then that the unit is definitely 'bricked' and cannot boot almost certainly because it can't load the corrupt map image file.

I think that it may be possible to erase/overwrite rgn49, which is the region where the Primary detail map is stored named gmapprom.img, using a custom *.rgn file flashed with Updater.exe. I'll need more help with this from one or more of the resident Software Experts so hopefully one of them knows the SP2720 and will post with some info. In the meantime, can you check for sure that it's detected by Updater.exe? Please download the current firmware from here:

Don't run it. You need to extract the file to obtain to obtain the two files 040401000720.rgn and Updater.exe. If you have trouble extracting, rename 'StreetPilot2720_720.exe' to 'StreetPilot2720_720.zip' and then extract it that way.

With the 2 files in the same folder, drag the rgn file onto Updater.exe which will open, enable the radio button next to 'USB Device', then connect the SP to your PC by USB and power it on. Hopefully the window to the right will populate with 'StreetPilot 2720 [Unit ID xxxxxxxxxx]' which indicates that it can be flashed. If you want to fully test it and you're game, you can flash it because it's the current SP2720 fw anyway so it certainly shouldn't cause any further problems but it's your choice [who knows it might just sort it out if you reflash the fw, but i doubt it].

Good luck. If it can't be seen by Updater.exe then maybe it's toast.
