Thread: Garmin Oregon 6x0 Software Versions Summary

I tried old CNEU maps too, and some other tricks. No way. Sw looks for every CNEU version .gma.
No changes in maps, CNEU 2013.30 works with previous sw, it doesn't work with new one.

Loly, map after gimgunlock is unlocked. Working with previous sw, not working with new sw.

Any one tried this with Topo Pro maps ?
Same conclusion for the CN EU is already given for the new firmware upgrade for the Montana (5.60)

It works with Topo Germany pro v6, Transalpin , Italy Trekmap v.3 pro and new Bluecharts

Hi,

Apparently, only CN Maps are affected : Topo France v3 unlocked with gimgunlock is still displayed on my Montana with new 5.6 firmware whereas CN Europe NTU 2014-40 is not.
So is the problem really linked to .gma authentification (new topo maps have .gma authentification as well, haven't they ?) ?
I'm downgrading to 5.4 !

Anybody try change name of CN?

example:

If your unit see map Topo Benelux Pro , remove this map from unit and add name of this removed map to CN.
