Just thought i’d share this with you in case you’ve got a smart phone and were considering buying a sat-nav for the car. Nav Free is a free sat nav which has turn by turn voice instructions – i’ve got it for the iphone and its also available for android phones. I’ve used it for a month or so now & the quality is great – no lagging, always keeps up with your location. Highly recommended – but cant understand why its free as there doesnt appear to be any advertising on it.
