A personalization system for vehicles uses a CD player and a keyless entry transmitter. The CD player outputs audible prompting signals including accessory operation choices. The driver selects accessory operation by pressing the "LOCK" or "UNLOCK" switch on the keyless entry key fob following an associated audio prompting signal. A controller coupled to the CD player receives a selection signal from the keyless entry key fob and associates the receipt of the selection signal with an index corresponding to the audio prompting signal last output by the CD player. The controller controls accessory operation according to the accessory options selected responsive to the audible prompting signal.
