Thread: Nuvi 2x0 Software Versions Summary

You can read this threads:

[Only registered and activated users can see links. ]
and
[Only registered and activated users can see links. ]

For example you can backup and make gcd after it:

12 - boot.bin (0x0C)
16 - logo.bin (0x10)
14 - fw_all.bin main firmware (0x0E)

But I do not know about ldr.bin. Where do you obtain it?! As usually not released version is based on next released but not always. The best way ask in threads mentioned above...
