I can agree for model 34xx, but I don't know if it's applicable for 37xx model.

Interesting if we can add 3D Building ability/3D Terrain to 3750 or 37xx (lost model number) by just using .xml not firmware/memory patching.

I also know about restore/change model number by xrgn,41 from other unit.
I guess it's not a big problem for Alex (and he can restore model number easily by the other ways).

warning :: To do xrgn,41 from other unit may stop booting at Garmin logo and won't be flashed xrgn by card.,

Clearing region 41 you removes registration code and unlock codes too, all this data should be visible in GarminDevice.xml. The original map, that came with nuvi would become locked.

You can restore 41 if you have a backup form your device.

For me it works without erasing, but adding erase before writing doesn't interfere.

including regions 05 and 43?

Other region I can overwrite but not for 05 and 43.

I wouldn't try to erase or write regions with code. Better not experiment on 5 and 43 if you aren't sure what you are doing.

bpb, NEVER erase regions 05 and 43!!! Your device will be dead with 100% probability!!!

@Alexander2010, thanks for remind I will not erase.

just a question in mind before ever did full restore all regions and few region will not able to overwrite.
