I have a pioneer deh-1900mp car radio. How do I set the clock?

Answer 1

With the car key turned on:

Press "Source" and hold until the unit shuts off.

Press "Source" and hold until the function name appears in the display.

Press and release "Function" until the clock appears.

Use the << and >> buttons to select hours or minutes; use the up and down buttons to adjust the time.

When you're done, press and release "Source".

Answer 2

I just bought this unit. All i did was turn the car on and hold the source button until the stereo powered off. Then I held the source button again and the clock showed up. Then you just use the four buttons on the right. Enjoy!
