Just got a TomTom 5100 and it’s pretty good compared to my old Garmin It is a bit stripped down in terms of options or customisation but the lifetime world maps, traffic & speed cameras is a really good selling point. Speed limits on the mapping can be a bit out of date despite regular map updates but I have only had it a couple of months so that may improve. Got mine via Tesco points rather than keep getting restaurant vouchers for a change! Updating is very easy Via TomTom web interface and you can plan routes on TomTom Mydrive and send over GPRS to the unit as it has a built in data sim card. Live traffic is brilliant and very accurate, giving delay time, distance and offering alternative routes.
