Summary: This is my second 660, purchased to replace one that was hosed-up by Garmins Map Update Software. It does everything that I need it to do and more. Priced high, but need to have the ability to create custom routes for my motorcycle adventures and this unit fills that bill.
Summary: I have been using the Garmin Zumo 660LM GPS on my motorcycle for almost 3 months now. Background: I Ride a 2006 Harley Davidson Heritage Softail Classic with Vance and Hinds longshot pipes I commute each day to work (10 Miles one way) unless it is raining I usually do a long ride on the weekends (100 or more miles) Initial: The unit arrived on time and well packaged. There was no fear of damage.
Very good unit, but the software could use improving.

Summary: The Zumo 660 is probably the best unit for motorcycles. This is a replacement unit for one that was stolen. However, there are some software issues that should be addressed: 1. The software that Garmin bundles with the unit, BaseCamp, is atrocious. It is probably the worst software package I have ever used. It is buggy, clunky and unintuitive. For example, there is no way to easily modify a route so that you can take a non-direct path.
Overpriced but not much choice if you want the best

Summary: I moved up from the older Zumo 550. So far it does everything I need. No issues with software updates - you need to do these since you don't know how long the unit you get has been on a shelf. Used so far in a car, motorcycle (rainy and cold) and a snowmobile (0F and snowing). Coat the big connector on the back and the mating connectors on the harness with a dielectric grease to ensure good, dry contacts.
Summary: It's just a piece of plastic, designed to keep water from going into the pins of your Garmin mount. Seven bucks is expensive for a piece of plastic that just cost pennies to make and mold; but what can you do. It works well for it's intended purpose.
