Montana 610 not recognizing map

[doncleve]

I have a copy of blue chart g3 map, I can view it on several gpsr’s but on the Montana it gives me error to contact provider, is there anything I can change on the Montana to be able to read the map? Thanks

I don't think you will be able to use the Montana with Blue Charts, here are the compatibility lists :-
