im thinking of getting one of these sat nav thingys for my car, but to be honest i know sod all about them!
im assuming that they work like this:
you bung in the postcode where you are and where you want to go and it tells you when to turn left, right, etc.
i want one that i can take from car to car
can anyone recommend something that will do the job? im not looking to spent loads, say less than £300
