I was able to use EU maps on the RHB17 430N model (locked to NA maps only).

Garmin software version 7.09
Head Unit software version 52.00.01

Previously I was getting:

Code: Select all

The map update provided is not compatible with your navigation system.

Still needs a little more digging into it but now the uploaded map CN Europe NTU 2024 works and unit navigates well.

Have to find our how to delete it from there now as once uploaded can't be removed. Found a way to delete uploaded map.

Right now I have CN Europe NTU 2024 as my gmapprom.img. JCV works fine too.

Still to find our if some Lang/Keyboard/Voice other than US possible.
