Garmin Varia RearVue 820 review: by far the best radar light you can buy, but you'll need a recent Garmin GPS to get the best out of it
· By Endurance Wire
The RearVue 820 incorporates new tech that elevates it far beyond everything else on the market Best-in-class radar performance; lane positioning; no false readings; vehicle-size identification Needs a recent Garmin head unit to exploit the best features; not cheap; not as large a light lens as some Garmin's Varia RearVue 820 is more accurate than any other radar light available, although you need to pair it with a recent Garmin GPS or Garmin’s app to get the full extent of the new features.
