Yep, great feature and you can save your routes on your desktop. The only problem is you can’t access them from an iPhone. So I share the link to myself in an email. Then you can open the route on the iPhone.
And you can save a Tyre route in Google Maps (on the Tyre menu). That’s what I do for a backup, then email myself the Google map link so I can open it on my phone, just in case I lose my GPS (or I’m in Mexico where the Garmin is worse than useless).
