Many thanks for the input, chaps. (And perhaps, Chapesses).
Some years back, I was going to a meeting with the Non-Exec Chairman of my software company, in his sparkling new top-end Lexus; which enjoyed the very latest built-in SatNav.
As we galloped along a brand new link road to Chelmsford (Essex) over what had been fields not long before, the SatNav became very, very confused!
Seems on balance, Garmin is the way to go.
Apols for not reverting before: have been at out French home, wherein the Boss insists I do not have a PC and broadband as "You won't get any work done!"
