Unfortunately, the setup seems to be less than reliable. While it seemed to be working fine after I got done with Garmin support. It went south again. I played around and got it back working. It seems to be very finicky. While maybe there is something wrong with either my Edge 530 or the Varia. This feels a lot more like a software bug. I'm thinking Garmin screwed something up in an update. Or the setup is just finicky (i.e. a bug you can work around) and once I get it working it will stay that way as long as I don't look at it wrong.
