I recently had the Geek Squad at Best Buy install a Viper security/keyless entry on my 02. There is a feature that utilizes the system for a turbo timer. it is able to be set at 1,3 or 5 minutes. When using the system it continues to run with the key out of ignition, but it is almost like the ignition is still on when the truck turns off at the timer. The radio and such stays on as if you turned the truck off and didnt open the doors. Is there a setting that can be changed at home or at the dealer ship to have everything turn off with the turbo timer. I am looking to utilize the turbo timer on a regular basis with the comfort of walking away from the truck for hours and know that I will not come back to drained batteries. Thanx.
