    Unhappy Print screen of errors

    Document attached gives links to my errors while trying to get the unit to exit its rebooting mode. Hope you folks can open the file and BTW I'm from the South shore of Montreal, Quebec

    Yeah, well you wouldn't be the first Canuck who's been accused of being a Yank. Anyway, who's ever heard of THAT South Shore so you'd understand why i thought you were from MA.

    I think your screens are only showing the map products associated with your 2720. The error screens i was referring to would look something like this:

    Anyway, unless anyone can suggest a way to pause the boot [like a cure firmware] so that WU can hold the connection that WU bat file method just ain't gonna work.

    @kunix
    What about QuickCure3, any chance it can be used/adapted for these old things?

The GUI should not open, it should simply immediately invoke the progress window only. No wonder you couldn't get it to work, it would take ages for WU to open it's GUI, etc. I've just tried the BAT file again to load Rarotonga gmapprom to rgn49 on mine. It worked fine, no GUI showed just the progress window instantly popped up and reporting erasing [the 251MiB AUNZ map] and then it loaded the little map, all in a few seconds. I'm now replacing it again with AU/NZ, no problem with the GUI opening went straight to the little progress window.

    I guess that's Win 7 on your PC by the pic. Mine is 8.1 64bit. Try right clicking the BAT file and quickly selecting run as Administrator which will run it with elevated privileges but then you'll have another window to click thru for that too, which will slow you down. I just don't understand why the GUI is opening using the BAT file command. You could also try running the command manually using command prompt, open it as Administrator and have the command text ready in the DOS box to hit enter when the SP connects.

    Excellent! Waiting for your report on the fix.

    Neil, good job!

    I saw in your hex compare screenshot that you actually edited it to "49" in hexadecimal system. In decimal system that would be 73. Usually when we talk regions we talk in decimal system. The updater.txt commands also use decimal system. So on Nuvi's I got, system/storage is in Region 48. In a hex editor that would be "30" hexadecimal. So I think in your case 49 should be 31 in a hex editor. Unless its Region 73d then 49h you have is correct.

    To make it simple, safe and easy, kunix made makergn.exe for creating rgn files.

    Use it in cmd prompt type:

    Thx flagmax. But like i said i didn't know what the heck i was doing in hex with the region number and just 'lucked-in' with the change for the Pacific basemap using 03 for 3 being that 1-9 in decimal is the same in hexidecimal. Woohoo!

    So by thinking that the regions in hex were the actual regions numbers [how could they be, when there's 255 regions in a nuvi nv, duh!] i stupidly flashed that little gmapprom to rgn73 when i set the region# as 49 in the hex editor .... Brrr! Hope it's unused or my half-stuffed 2720 will be dead as a dodo if it tries to read from 73 at some point. The good news is that i've managed to clear whatever was stopping the secondary map gmapsupp working. I sent 'C:\Garmin\Sendmap20.exe -e' several times and now the secondary map works after it's loaded. Strange it couldn't be erased using the 'Erase maps in GPS' button on sendmap's GUI nor be overwitten before.

    Further emboldened after your enlightenment i've made Ratatonga as an RGN using makergn.exe and the command 'makergn.exe gmapprom.rgn 49 gmapprom.bin'. I've not even an iota of an idea how the naming of the bin and/or resultant rgn files affects the naming of the primary map img written to rgn49, but i know that it has to be gmapprom.img in there so better to be sure than sorry. I didn't want to end up with some other img name and cause more problems. I know i said i don't expect you blokes to give me hex lessons, but if you know under what name the img would be stored if the rgn file is named, say, output49.rgn i'd like to know. Maybe it's somehow magically changed to gmapprom.img anyway regardless but if it gets stored as output49.img then it's not only unreadable it's worse than useless 'coz maybe it can't be overwitten by a correct gmapprom.

    So just as a test, i then made my little map into an RGN using gmapprom.bin in RGN_Tool, changed the region# in hex from the default 33 to 31 and saved it. The two images files are identical in hash and hex compare. I then used Updater.exe to flash the file to the SP and bingo, i have Raratonga as the primary map.

    Found another tiny map Norfolk Isl which i know for sure works as gmapoem.img in nuvi units. Changed the command line for makergn.exe to '50' and made a gmapoem.rgn and flashed it. Now have Norfolk Island in the unit's list of Detail Maps and it can be enabled/disabled [explanation for other readers: not all img files named as gmapoem appear in the list and/or are selectable even though they might work, depends on the map and some types won't work with that naming].

    So this can potentially be used for some curing of these old units. Certainly corrupt maps in regions 3, 49 & 50 can be over-flashed using updater.exe. Also voices, pois etc can be overwritten with 'good' versions if we know where they're stored. In SP2610 i think that voices are stored in rgn17 [that's 11 in hexidecimal, see? i'm learning], maybe the same on SP2720 [if that's even right for 2610].

    Importantly, does anyone know where gmapsupp.img is written to by MapSource/MapInstall/Sendmap20? I'm not game to use Updater.exe to flash a gmapsupp.rgn to rgn49 in case i break it. I'd like to keep this unit stumbling along for a while to play more with it. Maybe someone could look at the way sendmap20.exe deals with the image file to find where it's being flashed? I've done a [not case sensitive] search of both sendmap20.exe and MyMaps.exe in hex for region and rgn, and one for 'R' which drove me mad so many hits of course, the only likely result was an entry in MyMaps.exe of '3B' following '52 47 3E' which would be rgn59, but as it was in the list of supported files it's really only a semi-colon [;] in plain text i'm sure.

    Are any of you software guys interested in doing some investigation on this stuff? Also looking if there's any possible way to dump regions with commands to look what's stored where ...... please? I'm prepared to offer up my 2720 as a sacrificial lamb for tests.

    Problem is SOLVED. Loaded a few maps from NT 2015.20, sorry Neil can't go the RARATONGA way and made up a route with a couple of way points. ALL is well, working like a charm!!! Right clicking BAT file and opening it as administrator did the job right on first try!!
    Waves thanks from ''Snow in forecast for tomorrow Montreal. Thanks to all and sends a G'Day to you Neil!!

    Sorry to have put you thru clicking the BAT file dozens of times before. As it now turns out after flagmax put me right on the region number in hex we could have fixed it by flashing a map with Updater.exe anyway. Glad you're sorted and much good stuff has come out of this thread for me. Hoping for even more to be shared by our brilliant NSEs yet!

    I've only been to Montreal in the summer. Just to spoil your 'sunny' mood following the resurrection of your SP, forecast maximum here today is 29C about 84F and it's not Summer yet. Overnight min expected 19C [~66F].
    Do you hate me just a little bit now?

    Neil,

    The names in my makergn example are irrelevant. You just have to know whats input and output. Only the region matters.
    If you run makergn without any arguments, you will see:
    Code:

    I am surprised that you can write .rgn made with .img file directly into a region and it works. Nuvi's are different from 2720 in that region 48 is actually a dos type disk image with a partition table that has files inside of it. Think of Nuvi region 48 like a flash drive or a hard drive.

    By now it should be clear I have zero experience with 2720 type Garmins.

    If you want to study what sendmap/updater sends to gps, install usblyzer/usbtrace and start logging. Wish you luck.

    I don't know how or if its even possible to dump regions with 2720. Maybe someone else with more experience can IDA the firmware to see the commands the device will respond too.
