I am referring to the symbol right next to the power meter symbol - any idea what this could be and how I disable it?
Looks like I need to buy a smart trainer now. ;)
Yep. Garmin bought Tacx in February 2019.
Last Winter, I used the indoor trainer profile with an ICG IC7 bike at a local gym. It may be a while before using the gym is an option, so I am considering a smart trainer.
Yeah. Using the smart trainer a lot more since Covid. Though I've experimented using the Garmin with it, I basically just use my computer/tablet to control and record the trainer with Zwift, Trainerroad, Rouvy, or whatever. For me, there's no benefit in interposing the Garmin.
