Audio Systems: setting the clock, cursor buttons, pioneer mosfet

Question
I bought a truck with a Pioneer Mosfet 50 cd player installed in it. It came with no manual. I have tried a hundred different ways to set the clock but cannot get it. Can you help me out?

Answer
Try this, its for most pioneer models:

1. Hold SOURCE button to turn unit off. Only the time will be displayed at this point.

2. Hold the F (function) key for 2-3 seconds (located at upper-right corner of head unit).

3. The hours digit will start flashing. Use the UP and DOWN cursor buttons next to the F button to set the hour.

4. Press the RIGHT cursor button. The minutes will flash. Use the UP and DOWN cursor buttons to set the minute.

5. Press the F key once more, press the SOURC button to turn the unit back on, press the CLK button to toggle the time display on or off.

Let me know if that works please.
Good luck!
