I've recently purchased an R1200RS it is fitted with the nav mount and the 'wonder wheel' I have a NavV which I have used on several different bikes over the last 10 years and it's always been reliable. My question is, when it shows the mileage on the Nav, is it showing the total mileage that the device has travelled or the total mileage the bike has travelled? I don't know if the nav recognises the BMW that it is connected to.
