Best way I found was simply to sit in the car for an hour or two and have a play with the menu options - I'm no whizz when comes to technology but its all quite logical once you find the options available and when you do need to plan a route the clarity of the instructions and viusal guidance are extremely good. Mind you, I had the car about 3 months before I decided to sit down and fathom it out
Thank god its not just me then .......................
