I will try to keep this article updated with any major features, functions or fixes that Garmin release for the Monterra. It's worth spending time discussing the Display given that it is the primary human interface with this device.
If you don't have a late model smartphone, you wouldn't know that Projected Capacitive touch (PCAP) displays are not particularly glove-friendly.
These are not insignificant features when it comes to Adventure and Dual Sport Motorcycle use.
The 4" multi-touch display has the same resolution as the Montana (480x272) so if you're comparing it to todays high-resolution smartphone displays it's not even close in terms of pixel density.
NOTE: As I describe software features and functions throughout the article, please keep in mind that Garmin has a history of updating the software for their devices on a regular basis to fix bugs and sometimes add new features and functions.
That means the operation of the device may change at any time -- usually for the better.
The only external ports on the unit are an Audio Out 3.5mm Socket and a mini-USB port.
