A quick look on the web isn’t very revealing but, looking at the features available on these Drivesmart devices, I think they probably are Android based, like the Zūmo XT. Garmin seem very cagey about revealing their adoption of the Android OS - I haven’t a clue why though (maybe not wanting to frighten off users of iOS?). If I’m right, then they should be able to use .gpx 1.1, but trying 1.0 might just sort you out (backwards compatibility).

Of course, thinking on, there is also the Zumo XT (GPX 1.1) option in MRA Connector’s ‘select your device’ dropdown. That has to be worth trying too. Maybe I should have thought of that as an option earlier, but I hope I’ll be forgiven as I’m still using a (apparently horrendously ancient😏) Zūmo 390 perfectly happily and with great reliability!🙂Again, I haven’t a clue why the XT needs its own ‘special version’ of what is the global standard file type??? But then, Garmin should've been using 1.1 for many years yet chose to stick with 1.0 until very recently, so maybe they just think of themselves as a bit ‘special’!

I hope one, the other (or both) option gets you sorted out.
