Upgrade Your Tread Equip your compatible Garmin Tread„ with Group Ride Radio to get powerful functionality that your GPS can™t pull off alone”or replace the Group Ride Radio you destroyed somewhere along the trail. You™ll be able to track and talk to up to 20 other riders at the same time. It™ll make your next off-road adventure with the crew less like herding cats and more like a pack of lions on the hunt. Stay Connected Even Miles Apart The Group Ride Radio helps you stay connected no matter what the trail throws at you. It has a range of up to 2 miles, so even if your buds œaccidentally leave you eating their dust, you™ll be able to find their location and rendezvous. It™s water resistant too, so you don™t have to worry about crossing creek beds or standard trail mud (but maybe avoid scuba diving). Two Different Mic Options You™ve got two options when you™re using this radio: the included hand mic or a hands-free Bluetooth connection. The hand mic has great sound and a retro, ham-radio-esque look that makes you look like you mean business. If you™ve already got a helmet with a Bluetooth headset, you can use the Tread app on your phone to connect it to your Garmin. That way you can use the Bluetooth connection instead of the hand mic.
