I have the Zumo 550 and love it. Water proof, shock resistant, made by a biker for a biker. Got about 10k miles on with it and no probs. Even blue tooth so it talks to you on the bike with a blue tooth ear bud for a cell phone. Yup like mine.
the 550 is a well built unit so no probs there, the screen is really good on the garmin, theres a couple of things that i dont like, the count down to the next turn is not very accurate, and it would be nice to have an idea what the next command is, ie roundabout, turn right etc. Other than that the unit is really good, themain reason i bought this though was it also has an audio out jack plug so it can be connected to the aux of the 1800
I am in the process of going WIRELESS on my GL1100. In doing this I added a Zumo 550 and am pleased so far. The have a software package that allows you to map routes on your computer and then download. I also am using the XM radio that is built in the Zumo and that is nice. The only downside so far is with the wireless headset ( bluetooth ) there is a volume loss. I have an amplifier on order but haven't fixed that issue yet. My direction was no wires, computer downloads of trips, XM radio, wireless headsets. Still a work in progress!!!
:waving:Two months ago I purchased the TomTom Rider2 which is 100% waterproof and comes with a blue tooth helmet headset and a power cabel whichIwired tothe accessory terminal of the fusepanel. I bought it online from "tigergps.com" for a price of $399.95 plus $7.95 shipping.It has all the features that I need and is a lot cheaper than the Garmin Zumo 550. I am completely satisfied with the Rider2 and recommend it to anyone looking for a GPS for their motorcycle.
I have the Zumo 550 and I like it. One problem I have is when using it solely on battery power it sometimes shuts down. The battery housing cover is poorly designed and the battery can move about and lose contact with the terminals. I had to put a piece of cardboard off a cigarette packet between the cover and the battery to solve the problem. But otherwise I am happy with the 550.
