Garmin does offer me a 18.10 firmware upgrade for my Montana 750i, but I am not able to install it via Garmin Express, as it reports an error 500 and the GCD cannot be downloaded by Garmin Express. Garmin support is notified. Also changelog is not shown to me.

This update installed successfully on my 700.

I installed the firmware on the Montana 700 via Garmin Express and everything works fine. I have now found 16 geocaches with it. The navigation is very accurate. Even under the trees.
