I have recently upgraded my TomTom to a Go Basic 5" screen with wifi capability. Having just returned from a 3 day break we have discovered that the maps do not show the lane changes at all the junctions, although it does at some. Also it completely missed a junction where there were three options, all leading in different directions, and if it had not been for the fact that we were nearly home this could have caused us to add many more miles to our journey, which is not what you expect from your sat nav. I tried to check for updates using my phones wifi as it was advertised as not needing a computer to update and it would not connect. Has anyone else had the same issues ??
