Hello I have owned 2 Garmin nuvi sat nav over the past years and neither is able to load routes. (you can add the odd wey point that is all. Loading routes for holiday routes would be a major advantage. Currently I just keep adding a new destination to force it down a route I want. I understand that one uses "base camp to produce a route". Garmin have advised me that the LM51 Drivesmart will take routes. However Amazon reviews say that it cannot??? Any ideas. I do not want to buy yet another sat nav that will not take routes.
