I have a TomTom 720. I bought it nearly three years ago. It's good, and does what it says on the box. However, I feel I need a new toy...... What can I buy which: 1/ gives me Sat Nat 2/ OS maps 3/ Suitable for walking 4/ Bluetooth for the mobile Budget? Dunno, but maybe £200-300ish....? Ideally, small enough to go in my pocket when walking but big enough to be useable in the car. I don't want anything (such as a phone-based toy) which is on contract. I don't make many calls/texts and I'm happy on PAYG. Thanks!
