Does anybody know how to extend the time that the touch pro stays on without the ignition being on. When I am washing the car I like to listen to the radio. Pressing the button to activate the radio only leaves it active for around 5 minutes before it switches off. Surely there must be a setting somewhere to allow me to increase the time it stays on. I've searched the menu's and hand book but can't find anything. TIA.
