Likely your suspicion is valid.

It, like regions 41 and 154 before, contains UnitId and references to maps installed in the device.

Is rgn13 encrypted like the NV region of modern automotive devices and did you need to de-crypt to see UID etc.?

No, region 13 is not encrypted.

Hi
I need help creating Update.txt
Garmin Nuvi 2598 (HWID 1582) (V.4.8)
When installing using SD (Garmin/GUPDATE.GCD)
installs and writes that update V.4.8 is installed
(at the same time I install V.5.5)
I installed LOGO using SD (Original and Custom), everything is OK
(The PC does not see the navigator)

Hi!

Is there way to backup regions for Alpha 300i?

How to extract Ldr.bin file from software GUPDATE.GSP file?

HWID is 4335 for K version.

Likewise for this example.

If you don’t figure it out, send me the GUPDATE .gcd file and I’ll prepare it.

@IZK

Ldr.bin from GSP file, not from GCD.
