China NT on a Montana 610t
« on: November 09, 2017, 05:55:01 PM »
I've seen folks say that they have done it but garmin tech support says 'it is not listed as compatible'.

Anybody here had luck with it? I don't want to drop $100+ and it not work.

Thanks

Not sure if it is still the case, but China maps used to have a variable error in the data.  You needed a Chinese market GPS to correct the error.  Some strange China government requirement.

Someone had figured out the algorithm to correct the error and was providing corrected versions.  Not sure if that is still the case.  I used to work in China a lot and had used that version.
