Neil, good job!

I saw in your hex compare screenshot that you actually edited it to "49" in hexadecimal system. In decimal system that would be 73. Usually when we talk regions we talk in decimal system. The updater.txt commands also use decimal system. So on Nuvi's I got, system/storage is in Region 48. In a hex editor that would be "30" hexadecimal. So I think in your case 49 should be 31 in a hex editor. Unless its Region 73d then 49h you have is correct.

To make it simple, safe and easy, kunix made makergn.exe for creating rgn files.

Use it in cmd prompt type:
