I have an pretty old wireless sensor on my racebike. When the bike is static the device automatically stops. On the tom tom I have to press the stop/start button and this can be pretty frustrating if I forget to stop or start the watch at stops. Its also pretty difficult to do for short stops ie stopping at a junction or roundabout. Whilst the tom tom is more accurate distance, I am using the old device for time. This works for my own info but obviously is inaccurate when uploading data to my laptop. Is there a function that will stop the watch when the bike is static?
