TomTom has release an update to its iPhone and iPod touch navigation app adding an improved traffic service and support for multi-stop routes. TomTom 1.8 adds a new optional “TomTom HD Traffic” feature available as an in-app purchase that provides more accurate, real-time traffic information, updated every two minutes. The new version now allows users to create routes with up to five stops and includes an update to the latest maps. Version 1.8 also drops support for the original iPhone and first-generation iPod touch, noting that users of these devices should ensure that they do not delete the prior version from their device. TomTom is available from the App Store in versions for different areas: TomTom U.S. and Canada ($60), TomTom U.S.A. ($50) and TomTom Europe ($120) along with versions for several other areas. TomTom HD Traffic is available only in the U.S. via in-app purchase for an additional $20.
