He have working nuvi 3760 converted to 34xx and 3750 with touch panel problem.
As having made a reg 41 backup of my 3760 before flashing it to 3490 I used WinHex to find the device ID in the 41.bin file, but I was not succesful.
Maybe the ID is crypted or stored in another reg.
I also have a 3750 (unfortunately with a defective LCD/Touch), with this device I would it risk to patch reg 41.
