I should mention I have a 550, 396, 590 already. Received the XT, went through Settings, all looks familiar as the 590, set my preferences. Firmware version 2.90 noted.
Installed new SD card, plugged in USB (Windows 10). Garmin Express opened, informed me of update, I ignored, went to register the XT. GE crashed, restarted, no prompt for update, registered the XT. XT updates listed includes 6.1, I'm choosing to ignore until all the dust settles.
I noticed under the map update the option to install to computer and device, but I gather that is not for real based on prior comments..........
Screen is nice as I expected, not impressed with the cradle lock, they could have done better IMHO. Going to install backup tether when I can find one. Going for a test ride tomorrow with a newly created route in BC. I will ensure completely locked in cradle before departing. Installing my usual Glarestomper sunshade. Still have to pair up phone and headset and see what this Garmin Drive app is all about.......
