How to backup Nuvi NV (region41) with sd

**smokefree** · 14th February 2014, 10:29 AM

Currently I am in the process of backing up rgn 41 on all my nüvi units. Successful so far on all 2xx and 14xx units. Now I've come to the nüvi 2545. I've got the correct Ldr.bin file inside the X:\Garmin\Updater\1371 folder. However, when switching on the unit, it hangs on the Garmin splash screen with the text "Loading Maps" at the bottom of the screen. It stays there until I manually switch off the unit (or until the battery runs flat). No 41.bin file in the root of the microSD and no update.log file in the \1371 folder.

Few other topic related questions:
1. Can a backup of rgn41 be made on hand held Garmin units as well, eg Oregon, Montana, Dakota, Edge, GPSmap, etc?
2. Is there a list of rgn numbers and their purpose? In this thread focus is on rgn41. What are other regions used for and why not back them up?

You don't need other regions only 41 is important.

16 is logo, 5 and 12 is boot.bin that you find in gcd file in new nuvi 140 is for enable feature, so only region that you need if something go wrong in your nuvi is region 41.

Thanks Loly. Remains the question: how come backing up rgn 41 of the nüvi 2545 does not work?

I did not mention it explicitly in my previous post, but the unit is not bricked. It works fine, just the backup procedure does not work.

in update.txt write this and scan will work

rrgn,41,2:/41.bin
reboot

Old nuvi use 1 for SD card but new nuvi have 2 for SD card

Loly, smokefree has a 2xx5. It's the 2013 2xx7 devices which have the RWFS which is written as 1:/ and the microSD as 2:/. The 2012 range 2xx5 definitely still has the path 1:/ for the card.

@smokefree
Try another microSD. Format it freshly first before adding the Garmin/Updater/1371 folders and also remake ldr.bin. A hard reset or clear NV of the unit would also be advisable before you try again. My 2455 and 2595 both HWID 1371 have no problems writing regions to the card.

This initially appeared to be working (SOFTWARE LOADING / LOADER message, green progress bar and reboot) but did not give me a 41.bin file in the root of the microSD and it resulted in a corrupted update.log file (unreadable).

Used another microSD, cleared NV and tried again (using 1:/). All symptoms look fine, this time I even do have 41.bin in the root, but the update.log file is still corrupt.

Edit:
The 41.bin file on the microSD also seems corrupt as I am unable to copy it from microSD to the HDD of the PC. Will try a third microSD and try again but will not be home until 8 hours from now. Could it be the nüvi 2545 does not write the files properly onto memory card?

I'm glad I found this post!
I just tried to back up region 41 for my 2557LMT (2013 device), with
rrgn,41,1:/41.bin. no backup.
After I changed the number to 2, 41.bin was created

Also you must have backup for this case too:
rrgn,41,1:/41.bin
But this would be located on RWFS drive but not SD. I think you can find it there (in RWFS) even now.

I just enabled "Show RWFS In Mass Storage" and saw 41.bin file on the device root folder mounted on another drive on a PC. The backup was created the first time I tried rrgn,41,1:/41.bin, but I didn't know that.
Thanks!
