You cannot simply add a truck profile. The functions are in the dezl firmware so the only way is to convert.

The devices nuvi 2797, dezl/Camper/RV 760 are identical hardware with differing HWIDs. Theoretically full conversion from any of them to another should be possible however the safest way is to first try a 'hybrid firmware' made up of the Camper 760's boot.bin combined with the rest of dezl 760's firmware components and retaining the Camper's HWID. If that works successfully then a full flash of complete dezl firmware should be safe. If a hybrid flash doesn't work and you get 'system software missing' message or there are weird results then a flash back to Camper firmware is easy because the Boot BLK and X-Loader regions have not been overwritten with the dezl boot.bin (which may well be the same data with just a different HWID anyway, I haven't checked).

In some cases hybrid fw won't work to convert successfully but a full conversion does, 37x0 to 34x0 is such an example. Doing a full conversion is more likely to give all desired functions however might also irretrievable brick the device. I'm sure the conversion has been tried many times before so perhaps someone might post about their results.

Thanxs a lot for your kind reply!can you provide me the files ('hybrid firmware' made up of the Camper 760's boot.bin combined with the rest of dezl 760's firmware components and retaining the Camper's HWID ) I need to make this conversion?

My PC is down at present and I'm also quite busy with other projects. I can make it for you but it means having to download both firmwares again as I can't easily access the copies I have on my fritzed PC.

Solutions:
1. You can do it yourself using RGN_Tool.exe (link below) to blend the fw components, or
2. If you don't feel confident to do that just post again and I'll make it for you when I have time in a day or so unless someone else does it beforehand.

Code: Select all
