I purchased a sat nav for touring around Cornwall, the added benefit being it had a speedo, although as stated earlier, I am not wholly convinced it is accurate - going by road side speed warning displays.
It is also a bit too much hassle for every day trips.
I did think about adding a digital readout that connected to the ODB port, is this worth it though? Would the data from the ODB port be more accurate?
Appreciate any guidance.
