I have just purchased a 2003 Buick Rendezvous. I use the front cabin power outlet (cig lighter socket) to power my Tom-Tom GPS. It has a convenient shut-down function that allows it to turn itself off a few seconds after external power is removed. This worked very well in my previous car. The Rendezvous manual(3-24)states that power to the accessory outlet(s) will shut off about 10 minutes after the car ignition switch is turned off, but mine stays on. I'm sure the GPS would run for days on the car's battery but I'd like to have it shut down when the car is off, like the radio does. Can you offer any suggestions? Thank you.
