Thread: Enable 3790 features on your 3750/60

If you do not want/need to use a different firmware, just follow these steps to enable the 3790 options:

1- Find your current firmware for your GPS (gcd or rgn)
2- Open it in RGN_Tool
3- In Tools, run the 3790 patch
4- Save to rgn
5- Drag the new .rgn over updater.exe from Garmin
6- Put your GPS in service/pre-boot mode with USB cable
7- flash by clicking Ok in updater.exe

For more details about flashing and pre-boot mode, see Step 3 & 4 at the bottom of this thread:
