I can't speak from experience of the latest models but my older Garmins (305/705/Dakota) play nicely with Debian (and Android). I believe most of the newer devices will mount as a USB drive.I must admit I've been wondering if its time I handed in my trusty cycle computer and got myself a Garmin, only wondering though, I rarely ride on roads that I don't know and I'm sure that getting the device and the computer to talk to each other will be a challenge, the down side of linux.
I'm always worried these things would hamper the performance of my rod brakes...I have never used a cycle computer. Being a minimalist who hates attaching unnecessary stuff to my bikes, I avoided them. Then I found myself carrying my skiing/walking GPS in a pocket to see where I had been and upgraded to a Garmin when Aldi were selling them cheap. Dead easy to upload to a computer and Strava. Even got Mrs A to use one, and she is a bit of a Luddite.
Be glad its taken you this long, I hear some of those can be a bugger to get rid ofDuring 2015 I have embraced quite a few more modern cycling aids ... Does this mean the start of the end for older technology like steel bikes!
So in 2015 I started using the following things, Sti's, Spd clip in pedals,alloy framed bikes, Carbon forks, Garmin 200 and just had a Garmin Virb for my birthday .
Do people think that this might be the start of something happening in the way I cycle?
