I currently have the TomTom app installed and for the most part it's great. However, I am finding it increasingly difficult to live with the GPS lag issue: I am constantly shown around 30 to 100 feet behind my actual position. This is bearable (just) on straight roads, however on roundabouts it's impossible to deal with. I assume that because TomTom are going to release the cradle with the extra GPS chip in, that they have no intention of trying to address this issue within the app. I have tried contacting TomTom about forthcoming plans, but they remain as tight-lipped as ever. Does Navigon suffer with the same issue?
