Can anyone help please. I have recently bought Honda cr-v 2000cc
petrol auto.
It is an imported vehicle, when it was imported the clock was in
kilometres,the the speedo front cover was changed for miles and the
speedo recalibrated.

The speedo however was not turned back to reflect the true mileage in
miles.
There is a letter from the supplier stating that when the vehicle was
sold to the person I bought it off that the mileage was 77896
kilometres = 44.083 miles.
Since purchase eleven months ago the owner has driven a further 5624
miles, the clock now shows 77896 kilometers plus the additional 53707
miles. I understand that it is possible to get the speedo clocked to
reflect the correct miles instead of kilometeres, and also obtain
details in writing why the change has taken place.
Could anyone point me in the right direction. thanks
