I have a TT One unit with IQ routes and I don't see the point in it. I frequently travel from South to North London and the TT ALWAYS sends me the same way which takes sooooo much longer than another route I already know of. If I go into the menu and prepare the same route for a Monday morning, Friday afternoon, Sunday night, Saturday in the middle of the night - always the same route. So the fact TomTom advertise these units to find the most suitable route based on date is a complete con. Do you think I have a leg to stand on to get my money back on the unit if it's 3 months old despite the fact I've given it a chance to prove me wrong? And yes, IQ routes IS switched on.
