    He have nuvi 3750

    We try to find out how to change model number on first screen and in garmindevice.xml
    I change in reg41 decimal 3750 to 3790, result is, 37xx in garmin device.xml
    Now i change hex string for 3750, we will se result tomorow.

    p.s.
    @Neil read all posts not only every other

    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.
