If I flash a Garmin Zumo 590 with the 595 firmware, it still displays the standard Garmin boot logo, so I suspect that even with the 595 firmware, it still loads from region 16 if that's where the Logo is. Only with the HD 590 does it change to the small error message after flashing. (The HD Zumo 590 and the Garmin Zumo 590 have the same HW ID.)

That sounds possible! But you are dealing with a stupid newbie here! :-) Can you tell me how to dump rgn16 with Ldr.bin and 'rrgn' text command, please? When I load the .GCD file into the RGN Tool, I don't see that region.
