The TomTom VIA 1535TM is the top of the line model in TomTom’s new VIA series. Sporting a wide 5” screen, the VIA 1535TM offers lifetime traffic and map updates (hence the TM in the product name). This model updates a previous unit, the exceptionally popular TomTom XXL 540TM, adding Bluetooth, voice commands and TomTom’s new Webkit-based interface. Like all units in the VIA 1xx5 series, this one comes with preloaded maps of the US, Canada and Mexico.
