Has anyone had any success connecting their Instinct to a Microsoft Surface - these devices have USB C ports only. Maybe it's a case of a USB C charge/data cable that doesn't yet exist? Or maybe there is a wireless way to connect to a Windows 10 device? [N.B. the Ant+ stick is a one-way syncing device so I don't think could be a solution to this.] What I want to do is to be able to send routes, etc. from my 'PC' to my Instinct.
An ANT+ stick is not one way. You need a USB dongle just like I have so I can plug my Garmin devices into/hard drive/usb stick into my android USBC phone.
