if the problem is particular to your cell phone, this wont help. however. there is a problem with the nav software. in order to display phone numbers, change destinations etc, while the tch is moving, you need to use the hacked version of the nav 5.1 or 6.1 software. the directions to create the hacked nav software disc and loading instructions have been previously posted in this forum. after loading the hacked version, each and every time you turn the tch on, in order to see the caller-id info while moving, you will have to use the overide function before you start moving. this will allow you to use all the functionality that the toyota geniuses disabled for our own saftey.
