Summary: The one sent to me was not a 450. It was a 550. Okay, I can live with that, but I had nothing but problems with it. First, it didn't have US maps on it, so I had to spend $50 to download maps. Then I had to Buy a $60 motorcycle bracket for it.
Summary: I've used this product for a couple of years. Garmin definitely makes the easiest to use motorcyle GPS. This unit does everything I need including playing MP3 music. So easy to use that I almost never use the built in satellite radio. The GPS is very user friendly, can't imagine going without.
Summary: I purchased this product with the understanding that it was refurbished, but was as good as new. Well , the maps on it were out of date, never brought up to date when refurbished, so I then had to purchase updated maps which cost over $100.00 .
Summary: I have been using the Garmin on my motorcycle for the last 2 years without issue. It has been through rain a few times over the 10,000+ that I have had it attached. I really like the route programming tool for the computer.
Summary: I have had my Zumo for about a year now, it has worked flawlessly. I enjoy riding remote back roads as well as highways and I have been pleasantly surprised that I have not yet found a "minimum maintenance" road that wasn't in the machine...I have always found my way home from all of my wanderings.
