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: The gps works as advertised. As all gps, review the roads before you leave on trip, the unit can not always keep up with your need to know. The voice is not loud enough for my 09 Kawasaki Nomad, requires a better headset or receiver than my chatter box. Be sure you buy from the original owner.
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 Well , the maps on it were out of date, never brought up to date when refurbished, so I then had to purchase updated maps which cost over $100.00 .
