I bought this Sat Nav with intention of using it on my motorbike and car. As usual Amazon never failed to impress me with their delivery service, 3 days ahead of their predicted delivery date which was fantastic. I compared this sat nav to the rest of the Garmins and for the price and spec, you got more for your money. I also compared this to the tom tom rider and the garmin zumo's. The tom tom can't be plugged into my bike intercom via the 3.5 mm jack, instead you have to rely on the bluetooth scala stuff which is'nt good for touring as you can't charge the bluetooth stuff on the move. The zumo's did have a 3.5 mm jack point so i could plug into my bike intercom, however, compared to the nuvi 765, the zumo's did less and you were paying double the price of the nuvi 765 just to be waterproof. I had read some of the reviews on the nuvi 765, about it crashing etc, however, I have now had mine for about a month and use it everyday for my 40 mile commute to work and have'nt had any problems. As soon as it arrived i charged it up and downloaded all the updates from garmin, however, for some reason windows vista does',t like the nuvi 765, it loads the software on to vista ok, but when you plug in the nuvi it recognises the SD card as removable storage but won't sync the actual unit with the garmin software, however, the unit does work with windows XP perfectly. Being a biker and using this unit is'nt a problem, the unit is thin enough to put in the map compartment of my tank bag. I also have a lighter socket which i put on my bike, so have permenant power, however it did last about 4 hours on battery power. The sat nav bit is as good and accurate as my old tomtom rider V1, if not better, the audible speed camera alerts (mobile and fixed) are fantastic and very accurate but does need updating as it does'nt show the fixed speed camera in my village, which has been there for a few years. Its also handy that it shows you the speed limits for the roads your on just in case you forget. The route planning bit is as good as my old tomtom and does as it says on the tin. I have'nt been anywhere long enough yet to test the traffic announcments so can't comment. The screen and colours are brilliant, the information is aagain brilliant, and i can even use it through the tank bag covers with my bike gloves on. I also use the MP3 player everyday and can say that the music quality considering its coming through a bike intercom is loud enough and very good. Overall: i wish i had bought a unit like this a few years ago instead of my tomtom rider, which in comparison seems very basic. Now i have owned a garmin, i don't think i will ever by a tomtom again. Hope this review helps.
