I've been going around and around about which Garmin should I get, but then I realized Adventure Riders actually ride off-road too! I don't care about heart rate or my power output while I am pedaling, but I would like the same mapping/speed functions as the cycling Garmins, although I am not worried about strapping it onto my bars. I can always stick it into my Camelbak and look at a basic cyclometer for speed and distance. And I would like the same GPS be my street guide as well, bluetooth/wired headphone as well. Can the Zumo handle both functions, as an offroad route tracker and as well as the street mapping?
