I have just bought a Note n-tec with the trip computer. Problem is the data is way out of what it should be. e. g. after a M-way drive it shows ave mpg as 9.6 & ave mpg as 2. Also miles left in the full tank as only 150 (I hope not ) Is there a fix ??? Can the software be reloaded ??? I feel sure someone out there has tackled the same problem.
