If all you want is basic point A to B navigation then go cheap, hope it works out for you.
The
Garmin Zūmo series are expensive but they're great because they're made for what we do, ride motorcycles! Most of you're cheaper GPS will navigate from A to B but don't offer many options on how you'll get there, they have a choice of Fastest, Shortest or Off Road route.
Amongst the Zūmo's many features, one of the best is being able to plan trips on your computer before you start and share your rides with your riding buddies (Check out
SundayMorningRides.com). You can search for or add food/fuel stops or even local attractions to your route. Then, transfer your route to Zūmo and go ride.
I too thought I could make due with a cheaper model, I'd bought the
Nüvi 265WT. The 265WT allows you to add multiple stops to the route, so I figured I'd be able to plan a route by adding the intersections of several roads I wanted to ride. Wrong, the auto-route calculator would take me to those intersections but always found a faster or shorter route to get to them, cutting out the twisty roads in between that I wanted to ride.
The Zūmo takes me exactly where I want to go via the roads I want to ride. If I want to go exploring the Zūmo records my ride so I can take it back home, load it on the computer and clean it up (cut out the U-turns or add stops) so I can ride it again. No more stopping to write down or trying to remember road names, the GPS tracks every move.
