I and probably a few other people who don,t have sat nav but want one and not sure which one suits would value your opinion on which is better suited for what purpose. As someone who has never used one all the tech jargon is hard to follow , so could you please in simple terms say which one you have,what does it do i.e sat nav/cameras/order a pizza etc, what a resonanable price is new and seconed hand and if you have to pay to either use it or download the latest updates. thanks for your coments im sure as usual they will be helpful to alot of people
