Three weeks after launch, the highly anticipated Garmin Varia RearVUE 820 has had a turbulent start, with firmware 6.34 finally fixing key issues I uncovered – the ANT+ distance overflow and missing speed dat.

In this video, I break down what’s been fixed, what still needs work, and why this flagship radar isn’t delivering the seamless experience riders expected.
