I have created (Basecamp software) a route on my City Europe Navigator 2012.1 with various waypoints. When I inserted the route in my GPSMap 62st and used this route by walking, when the device was ON ROAD navigation, the ETA was 1 minute (which is impossible because the whole route is 3.1km and takes 45 minutes with 5km/hr). When I use OFF ROAD, therefore the ETA is not very accurate however the device tells me that ETA will be approx 43 minutes.
There is something wrong here.
