I've only ever used Tomtom for car navigation geekery -firstly on my old pda and my wife's basic tomtom one unit. I'm about to press the button on buying an app for the phone but I'm aware of Copilot live premium and the navigon offering and there are bound to be others too. I'm keen on the idea of live traffic updates and reroutes whichever I get.
Has anyone used the latest version of some of these to compare against? If within reason cost was not an issue, which would you go for?
