Brilliant I’ve got Waze on my iPhone so will have that running, again thanks for the advice best I check my cash and get booked in at @CRS PerformanceMy speedo is under-reporting by about 5%. Quite easy to change, even with Carista, but I haven't plucked up the courage yet.
I always have a sat nav running, either Waze or in my case Sygic to tell me my actual speed when I'm on a road that 'matters', the M42 for example, lane cameras everywhere!
