I been using this for 2 weeks. First week was great so I purchased the premium version. Second week however it's trying take me down closed roads, it took me on a 10 mile detour to Winford trying to get to Bridgewater Rd in Bristol. I'm not saying it's rubbish but it needs a lot more improvements as it's actually dangerous at times when it gets the lanes wrong or tries to make you go right at left only junctions.
