SO I tried to use the travel via option from kingston London to cambridge and I entered M25 and it then had a huge page full of m25's to chose from?!?! I thought there was only ONE m25.. how am I supposed to know what one to chose? if I knew I would not need the tomtom but I could not get it to travel via that way as I had no idea what one to pick..
how do I know?
