Summary: There aren't too many options out there for motorcycle GPS systems. I think it's way over priced. I don't like Garmin's graphical interface. Especially when inputting an address because it doesn't put all the letters on one screen. You have to select the letter range first, so putting in city names or street names can take twice as long. It does have some nice features though. Auto-night colors when it gets dark out.
Summary: Really pricey for what you get. I've been using it on my Harley Road King to lead club rides for about 8 months. I honestly can't figure out what this GPS does that the average $99 Tom Tom doesn't do. Albeit, I do like the fact that you can record and play music from the included Scandisc. I also like how it logs trips, this is probably it's most useful feature.
Summary: Stupid expensive for five-year-old technology. Frustrating user interface, especially compared to Waze on an iPhone, which is what I uses for most navigation. I wanted to smash it in frustration just trying to enter a basic US address, never mind French Canadian addresses! Patience, is required and rewarded. Once you get the address in, it seems to do a reasonable job of identifying a route, though it is often in disagreement with Waze, which accounts for traffic.
Summary: I live in Tokyo, and with even a massive amount of required data the GPS holds its own. The complaint I have is that the port for connecting the USB cable is located inside of the enclosed battery compartment. What this means is that powering the GPS from a USB connection requires the lid to the battery compartment to be removed, rendering the GPS non-waterproof.
Summary: I own a 2013 HD Electra Glide Ultra Classic and purchased the Garmin Zumo 660 from Amazon because of the better price. HD has an identical version called Road Tech Garmin Zumo 660, but more on that a little later: Pros - ease of installation. I removed the fairing and with a friend, attached the Zumo 660 in about 10 minutes. Replaced the fairing and the GPS was up and running. I adjusted the brightness and it works great. No problems.
Summary: When I received the case I was a a little disappointed. It is a nice fleece/type lining, snug and compact but I can barely get the Garmin 5" inside it. I thought it would have given me room for the clip-on back piece too, but it didn't and has no place to put it so I have to carry it separately with the case (opportunity to lose it).
Summary: This cover is a nice feature, but you really don'e need it. The Zumo motorcycle mounts power plug comes with a cover. I got this not knowing that, and wanting to protect the power connections. By the way, it is easily stolen.
Summary: Just received my order. The carrying case fits nicely and will do the job OK. However, its pretty cheaply made for the price. It doesn't even have a sealing flap to hold the device in. Resembles a cheap case for eye glasses.
Summary: it is what it is, overpriced piece of plastic that covers the mount.. but I needed it and it works and there isnt another option. So if you need it buy it, over packaged piece of plastic, that does what it says it does.
Summary: Well I have used the garmin zumo 450 for about 6 years.. I felt it was time to upgrade. The 660 is ok, the lane assist and speaks street names is a very nice. The mp3 player is ok, but my zumo 450 with blue tooth adapter sounds so much better. I do use a cardio scala g4 with a Aria helmet with both units, The phone use is a definite plus. All in all its ok. But not worth the money. I ride everyday and just wished it worked as well as my 450..
