Previously had the Garmin 810, actually the better model, have, however, exchanged, and the Garmin 800 has fortunately not all quirks of 810. The cycling computer is great, 10 variably adjustable data at the same time, with a slight backlight in any light legible, but unfortunately several flaws in the navigation again. For some advanced users: At least you can turn off the turn by turn, making the route recalculation off through the Garmin also. Otherwise, yes every PC planned route is recalculated from Garmin, and then not even often corresponds approximately to the planned route, regardless of the number of waypoints. (Goes with the 810 not!) Of course, also has the 800 various problems, otherwise it would not be a garmin: - The color of the route shown in the map though can be selected, however when navigating no function, here is the line always appears in a not always optimally visible "purple" - One is forced to turn off the turn by turn, and to follow the line as a crumb trail, not really the point of a Navis, uphill this works still quite good, but the downhill you can sometimes easy to overlook a junction -The satellite channels mainly in the deciduous forest is unfortunately often interrupted, the Navi turns strangely at set "Pause at standstill" from, although one still has a magnetic sensor. funny? Can you deal but if you do not break activated at standstill, but break under a certain speed. Illogical but is - Virtual Partner, Garmin here compares the current driving time (travel time with net substracted breaks) with the total driving time (travel time + net peeled breaks) of the stored comparison Tour. So a couple of times and one is green front, too often red and you lose. But is not the whole point All in all, for just 300.- actually a joke, especially if you contacted the complete learning resistant support department of Garmin. Yes, we know the problem, no we have no idea whether that will ever solved .... Compared to the newer model Garmin 810 still better classes, so if you can do without the live tracking of 810, necessarily pick up the 800 !!!! To my knowledge, has the 1000 model the same problems as the 810, so stay away. All in all still a buy recommendation, but there are currently on the market to my knowledge no better device.
