A friend has a Pioneer head unit in her car - don't know the model number BUT it has a LCD screen with scrolling pictures of dolphns, flying jets, sound meters, etc. My question is how do you change the time on this HU. Thanks in advance.

 

Turn the unit off with the source button, then hold the function key until it pops you into the settings menu. That should work

 

press function repeatedly until clock appears in display , press < > to select the one to adjust it will blink , press ^ v to adjust the selected number. thats the directions for the deh-p7500mp . good luck
