Thanks for the replies. Broadly im making home deliveries in a 7.5 tonner all over the south east as far as Salisbury oxford and Norwich. so although I will probably end up going to the same area I wont go to the same house/ streets.
I found myself in a situation yesterday that a proper sat nav would of solved. I was stuck in a traffic jam and the sat nav decided to take me a different route. Ended up with a width restriction that was hidden behind trees at the time in rush hour traffic trying to turn round. As said I realise that satnav’s aren’t the boss but navigating/driving a new to me truck in an unknown area with the entire collection of idiots around on the first day is a little busy to be worrying about where I have to go.
im sure with time I will get used to it but in the mean time its an extra aid.
