USB C and solar upgrade to 830

I'm a casual cyclist already in the Garmin ecosystem with a Varia radar looking to update my 830 with something that has USB C. This was a pretty incremental upgrade, but worth it for me for the ease of charging with the USB C and also the solar charging. There's not enough solar for it to charge while using it though, just makes less battery drain. And you can't solar charge it when it's not on.

Lots of fun stuff to play with!

You really need to go online to garmin.com or garmin express to find out how it all works. Online instructions are good. There are so many functions!
