How do you set the clock on a 1987 Chrysler fifth avenue?

Previous answer: "Press any one of the six memory buttons and the volume control knob at the same time....Rotate tuning knob for hour.....depress volume to get minutes....use tune knob to set. Hope this helps"

On my 87 Fifth Ave, I have the aluminum-face AM/FM/Cassette unit with 5 memory buttons. To set the clock, I have to do the following: 1) turn radio on 2) set display to show time by pressing the volume control knob 3) press "Set" button to left of display; display will now show "P1" 4) press volume control knob again; hours will appear on display. Rotate tuning knob to set hour 5) press volume control knob again; minutes will appear. Set with tuning knob 6) turn radio off. Time will now remain in memory.
