It does not. That’s the RCT716.\nWorks best when mounted straight and not angled downward. Crooked mounting reduces detection reliability.\nBattery life varies a lot depending on mode. Day flash gets best runtime.\nRadar detects vehicles, not cyclists. In group rides, it may trigger on fast riders approaching.\nMost road riders who try it won’t go back. Biggest complaint is price, second is charging discipline.\nIf someone rides high-speed roads regularly, this is one of the best awareness upgrades available.\nIf rider doesn’t already run a head unit or smartphone on bars, pairing setup can frustrate them.\nFirmware updates occasionally required.\nThis is for pavement riders, not trail-only MTB.\n\u003c\/div\u003e","brand":"Garmin","offers":[{"title":"Default Title","offer_id":53101437583674,"sku":"GG-LIGHT-GARMIN-RTL515-RADAR","price":199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0745\/5735\/8394\/files\/LT0308-02.jpg?v=1772279081","url":"https:\/\/gograva.com\/products\/garmin-varia-rtl515-rearview-radar-taillight","provider":"Grava Adventure Corporation","version":"1.0","type":"link"}
