Hi All I am looking for a new sat nav that user friendly easy to set up. Which brand is best Garmin Tom tom? I currently use google maps on my phone and i love the fact that even though i do the same work route everyday on the motorway it tells me if there is traffic ahead and will divert me off the motorway if its very bad congestion. Is this a feature on standard sat navs? As my friends doesn't do this it just suggest routes when she types the postcode in but doesn't give her alternative routes whilst travelling before she hits traffic. Any help and advice would be great Also is Halfords the best place to go to get it from and have them set it up in my car for me?
