How to update maps on a street pilot 2720

**ultrasheer** · 27th December 2010, 01:28 PM

Hello mates and thanks for all your useful tips. This is my situation.

I've latest version of MapSource installed with the europe 2011.32 unlocked thanks to GMAP UNLOCKER. I can see all the Europe Maps without problems.

How can I upload these maps on my 2720? I've tried MapInstall and MapSource but I'm not able to delete all the previous maps on the 2720 to upload the newst ones. The software tell me that I've just 500Mb free on the unit.

All the legitimate upgrade I've done in the past were done using the Garmin DVD with a software CNEUNT2008.exe so I imagine that I would need something like CNEUNT2011.exe to delete the old maps and install the new ones.

Is this correct? There's any other way I can put the new maps on my unit?

I've also IMGMAPSUPP.IMG unlocked that it's supposed to be the file to be replaced on the unit but I'm unable to see the 2720 as a disk so I cannot in any way upload this image on the unit.

I really don't know what to do so any help is really appreciated...

I copy and paste from a post i've read on Smellybiker's Wanderlust Worldmap --thanks Hans for your post
coz I think you can try :

I've got an European 2720 and I also like to change sometimes the primary map on my Garmin. Well... just this week I found a solution on an Dutch forum. It's so simple...

You need this:
An SD card (at least 2GB)
An SD card reader, attached to your computer
City Navigator NT Europe (or whatever map you want) installed on your computer
The MapID from that map
WebUpdater.exe (you can find in the Mapsource or Garmin directory)

Let's say I want to change the primary North American map in a European map. First thing to do is to make an imagefile from that European Map. Start MapSource, install City Navigator NT Europe on your computer and select all the maps. Put an SD card in your computer (maybe you have to buy an SDcard reader,I've got an build-in at my Asus Eee). You can now send the maps also to the SD card instead of sending them to your 2720. Send the selected (red) maps to you SD card. Now you can take a coffee of three, four, or go painting your bathroom. It took about an hour and a half on my computer to send the map to the SD card.

Take a look at that card when it's ready. You'll see that MapSource have make a folder on it with the name 'Garmin'. In that folder you'll find an image with the name GMAPSUPP.img
Rename that imagefile to GMAPPROM.img and put it in a map on your computer, let's say in C:\GARMIN
Open a DOS box and go to the map C:\GARMIN
Give this command: C:\Garmin\WebUpdater.exe /upload_file rgn=XX path=C:\Garmin\GMAPPROM.IMG -autorun usb /unlock_check fid=XXXX pid=X /i (sustitute XXX with your map FID values)
Again it will take a long time to upload the file to your 2720.

But... that's all folks! It's simple as that. After this you have a new map on your 2720. The GMAPPROM.img has overwrited the original one. And you have still plenty of room for other material. If you send some maps thru MapSource directly to your 2720, those maps will get the name GMAPSUPP.img and won't overwrite your just built primary mapping.

Thanks Catymag, I've found this procedure, a little different, on the net and followed steps by step. It worked!!! Now I've my 2720 with the newst maps.

Here's the complete procedure so someone other can benefit and update his 2720. Credit go to blankman on the gpspassion forum. I've edited his tutorial.

Before doing this I inform you that I've downloaded the West & Central Europe NT 2011.32 Img Unlocked 1.75GB For 2GB SD from a Kor@l and then I've followed this procedure

1. Connect the 2720 with the USB Cable
2. Copy the gmapsupp.img (unlocked) that you've just downloaded in the C:\Garmin folder
3. Rename gmapsupp.img to gmapprom.img
4. Check to see if a WebUpdater folder is inside the C:\Garmin folder. I don't have it inside so I've copied the WebUpdater folder in the C:\Garmin folder
5. Create a new notepad document and paste this text in it

C:\Garmin\WebUpdater\WebUpdater.exe /upload_file rgn=49 path=C:\Garmin\gmapprom.img -autorun usb /i

6. Save this text file with a name you want but, IMPORTANT, with the .bat extension. Mine was named 2720update.bat
7. When you double-click the SP2720_Update.BAT file, a command-line window should open up on your Desktop, plus WebUpdater should open and report that it's erasing your old maps and copying your new mapset into your SP2720. It will show you a "percent complete" indication as it goes along. When it's complete, WebUpdater will end and close the command-line window with it, at which point, your SP2720 will now have a fresh set of maps.

I've credited the two people where I've downloaded the unlocked img and where I've found the instructions. Thanks again Catymag...

I'm unclear as to the 'RGN' parameter. This might be obvious but I can't seem to figure out how the value is determined? Thanks!

This process worked perfectly for me. I have updated several 2720s and they are all now running current maps.

Big thumbs up to ultrasheer.

Thanks!

The procedure work for me on my WinXP computer. Now I have a Win 7 64 bit computer and I can not get the .bat file to work. I have changed the path to what I think is the correct path "program files (x86)".

C:\Program Files(x86)\Garmin\WebUpdater\WebUpdater.exe /upload_file rgn=49 path=C:\Program Files(x86)\Garmin\gmapprom.img -autorun usb /i

Help . . . .

Hi guys,

a bit of post resurrection with this, but I am having issues with re-doing the detailmap on my Quest.

Whenever I try to upload the gmapprom.img file to my Quest 2 via the DOS command prompt, I get this error:

[Only registered and activated users can see links. ]

It would seem the unit thinks the T4A map is loaded when in fact it is not - how do I get rid of this?

It would seem I have managed to resolve the issue:

. I downloaded MapUpload from

Code:

Please Login or Register to see the links

. I ran it to upload the gmapprom.img file to the unit, and there weren't any error messages or complaints.

. When it was done, there were two Garmin mapsets present (2012 & 2013)

. I re-ran the WebUpdater via the command line

. There is now only one Garmin mapset, the 2013 one (which is how I wanted it to be)

. I will transfer the T4A mapset later

Getting the same error from WebUpdater as “Naks” I wonder: Does the MapUpload program access the hidden memory in SP 2720?
Trying to upload 1.9GB with MapUpload on a W7 64bit-machine stops because on “not memory enogh”. MapUpload reports 672100 kB available.
