Just read from this q&a that the XT can probably only use the Map it’s shipped with.
Any other region may not work even if purchased from Garmin.

The only alternative is to use Osm maps I think. Am I right?

No. Not pirated maps.
Sources of maps are from here:


NT Maps

Free Maps

Can the XT read unlocked/free NT maps?

Oh. To be clearer I wonder if it can read my unlocked NT maps of other regions from other Garmin Devices.

I understand it only reads NTU maps

Is the XT able to read USA maps on EU device?
Wonder if it’s locked by device region

V3.30 is available!

Contacted Garmin Support via chat.
They were very helpful and emailed me the v3.20 update file.

Funny thing was that the agent told me the latest update was v3.10 but when i updated it was actually v3.20.

Hope V3.20 resolves the frequent device reboot when phone is connected via bluetooth

Yes, for reasons unknown, garmin express doesn't allow me to update to V3.20...
Keeps indicating that i have the latest firmware...

it would reside in [Garmin Device Drive] "X:/.system" as a gupdate.gcd file as you download it into the device

would need help to extract the gupdate.gcd file

Cool thank you!
Can't seem to find it anywhere... hope it appears one day
