I have a TomTom one xl that I lose and then I purchase this one . the interface be identical which be great , but the device be far superior . I have find the traffic feature to be very helful , the lane assist be great and the road it choose be much better than the one xl . the only bad thing be the mount . I buy a arkon ttep115 TomTom EasyPort Windshield \/ Dash Mount and the combination work well for I .
