iPhone 3GS, firmware 3.1.3, LapTimer Pro V13.4
When entering Sensor list with the Tom Tom connected, LapTImer Pro will exit. If I do this same thing with no Tom Tom connected, the Sensor List works as expected. The LapTimer does acknowledge that the Tom Tom is present and in the GPS screen it shows connection to the Tom Tom. So far, only the Senor List does not work.
