35 could potentially throw the speedo off in the opposite direction thosat nav tends to give you a slightly higher reading than the speedo anyway, as long as you're aware of it, it's allll good
Haha, i'll be sticking to 40's then hah!
Oh really? i thought it was the dial that was 10% innacurate therefore if you were doing actual 40MPH then it would read 44MPH but a satnav would read 40MPH? Ahh well i dont speed so i should be ok!
