The in car satnav I had in my Toyota was very good at highlighting all the petrol stations at junctions other than MSAs and thus provided good starting points for finding better places to eat. I can’t understand why the Tom-Tom I now use does not offer the same level of detail, especially as it caters for a much larger userbase than the Toyota units do. Mind ewe, I,don’t think the savings from not using MSA add up sufficiently to justify the excessive expense of the built in units.
