The Tom Tom bracket also includes the GPS chip which is excluded on the iTouch and will cost over $100. The iPhone antenna is supposedly the metal ring around the camera lens. It may work OK if mounted high on the dash for maximum exposure. I have a Magellan unit that works well, but I would like to use my iPhone in Australia. Both Tom Tom and Navigon have Australian maps for iPhone. On Jan 16, 2010, at 8:37 AM, Gerhard Kuhn wrote: > TomTom has a bracket with an external antenna that is suppose to > improve things.
