I have used a garmin 305 for the past 10 years and its served me very well. However I had a 'big' birthday coming up and wanted something that does true mapping as well as being able to make use of cadence and separate speed sensor. I had a long hard think about buying the 820 or the 520, the non touch screen 520 would have been great if only it had mapping, so in the end I plumped for the 820. My initial impression of the 820 is that its very small and neat. It picks up the satellite signal quickly and really has so many features that it will probably take a couple of months to work out exactly what i want display on screen during the ride. Do note that some to the more advanced features expect you to have power pedals etc if you want to use the advanced cycling dynamics. I don't have these but still think I have more than enough information to keep me busy post ride. The unit and sensors were extremely easy to fit with all the sensors already paired with the device. Data transfer is so easy with wi-fi and if you pair the 820 to your phone via bluetooth you again have access to group tracking as well as live tracking etc something i plan to try in the near future so my loved ones can see when I'm getting near home. I bought the 820 in between Christmas and the New Year so had a bit of a wait to receive the unit after the Christmas holidays and an email from Vanilla bikes just to keep me updated on progress would have been nice (this may be just my impatience to get my hands on my expensive new toy!). However the 820 arrived fairly quickly after the hols and for the price I paid in the Christmas sale I'm very happy. So...I'm happy with the 820, very happy with Vanilla bikes, their prices and service and will now consign the 305 to mountain biking until the 820 has a few years on the clock

Received as an upgrade to my 510 which was lost after a collision. Light, bright, with excellent mapping - just what I was expecting and needed!!
