One for the car, not for biking.
I've had experience with Garmin and TomTom which I've either borrowed off mates or used in their cars, and the Garmin seems to be the most user-friendly; I didn't really get on with the TomTom. So, any particular ones people can recommend? A quick search for 'Garmin sat nav' on Amazon throws up ones which have generally positive reviews but tend also to be quite mixed; some one and two stars reviews also.
