I used the TomTom Vio on my 3W, will be fixed to the outside mirror.
This has lifetime updates plus radar warnings as well.
Unfortunately TomTom is not producing it anymore.
TomTom have an interesting view on 'lifetime'. I have three Tom Toms with lifetime updates that I can no longer update as they no longer support those models. They have decided that they are at their 'End of Life'.
Tom Tom is still my satnav of choice, having previously used Navman and Garmin, but I'm disappointed that they no longer do they're small square 3.5" ones
