Garmin’s latest RearVue 820 is technically impressive, but it isn’t the straightforward RTL515 replacement many riders wanted. In this video, I make the case for a Varia RTL525: USB-C charging, longer battery life, a better-positioned power button and the same proven radar behaviour, mount and US$199 price that made the RTL515 the benchmark.
