The invention is a radio inside a vehicle providing each of the multiple drivers to automatically pre-set her radio adjustment settings for subsequent use. In the case of a �family car� where parents and young adults in the family share a car, the radio adjustment preferences (e.g., volume, bass, treble, etc.) for each driver are likely to be different. The more drivers there are to this �family car�, the more difficult it becomes for each driver to enjoy the comfort this radio affords because of the speaker adjustments required every time one turns on the radio.
This invention reduces confusion and adds comfort to the drivers of the same vehicle in that when a driver returns to a multi-driver vehicle and turns on the radio, the radio adjustment settings that he had on when he last used the car radio will be applied to the speaker output. It is as if this driver is the only driver of the vehicle.
