Summary: For the price, it sure would be nice to have the bigger screen. The software isn't the friendliest when creating your own route, but I think I figured out a method. I have not used all the features this includes (Bluetooth, TPS, VIRB, etc.), but it does record your actual route.
Summary: After getting misdirected a few times by my rather inadequate (for the job) Garmin Oregon, while leading a group of 9 bikes across the Netherlands recently I decided it was time to upgrade. After much research I opted for the Zumo 390. It is excellent!
Summary: I was all ways a non-believer in GPS having spent 35 years using maps all over the world. BUT a mate offered the loan of his unit, and on a dark, wet, rush hour approaching La Coruna Northern Spain I became a convert.
Summary: Unit feels nice and solid,very good mountings for the bike,also includes car mounting kit. Always had Garmin sat navs and so found it easy to use. This also shows points of interest on the map screen i.e. fuel and services which is very useful.
Summary: Works great for a biker. I recommend routing the wire first before you connect it to the mounting (saves time and my mistakes). Having been used to a car Tom Tom it took a while to understand how to get the best. Screen excellent and really bright. Blue tooth worked well with my helmet set.
