Reply With QuoteGood morning,
one question: does each navigator have its own ldr.bin file? If so, how can I retrieve the file from the navigator?
I noticed that RGN doesn’t mention ldr.bin. I would like to extract region 16 and region 41.
Thanks

Any garmin devices which use proprietary OS like your Drive 61 use RGN/GCD firmware files and they have a boot.bin component contained in the fw file. "Ldr.bin" is just the "boot.bin" renamed and despite the default naming of boot.bin, it's the ramloader. You can extract it from any RGN or GCD file with RGN_Tool.exe, here: [Only registered and activated users can see links. ], or use [Only registered and activated users can see links. ]. There is no reliable way to extract the boot.bin data from a device's onboard region 12 (0x0C) which is a virtual region.

By "doable", you mean to correct the model ID after conversion as discussed in posts from #5, then i agree that quite likely, if it's fw based, it can be done but i don't know how. You clearly have the motivation, so if you also have some coding experience and lots of time to investigate and the key is contained solely in the device firmware, then it is doable. However, because it's reputed to be a 'closed shop', Garmin's proprietary operating system is not known to be modifiable like Linux-type systems on which it's distantly based. So, if rather than fw the key to changing the model ID is buried in the actual OS it's a probably a waste of time to try.
You say "I know for sure it's doable". How do you know that?'Thanking Posts' are banned.
