Hi all, has anybody got the sp on the trip computers fitted to this model. Mine continues to show av mph as 29, and av mpg as 24.5. This even after resetting whilst on the move. The oddometer part of the setup seems to be as accurate as the satnav (Tom Tom), its just the rest of the info seems to be on another plant. My 38 is fitted with 18" alloys, ( L/Rr) and has 255/55/18 tyres. Hoping some one has an idea as to what might be the problem, Thanks Bazz. :boohoo:
