cuz i bought a car with that deck a sub amp and 12 disk cd changer but dont know how to turn it to cd changer mode

does anyone recall?

 

its a press and hold button not sure what one off hand.Then it is the tuner number buttons if equiped or the crosshairs if equiped for disk change.I wave been in to Pioneer from 1986 so I can help more with a detailed picture if one of the above is not it

thats the r model mine has supertunerIII where the cd's are on that picture

 

hit the source button to get to it..If it shuts off or only goes to the tuner and tape let me know

 

when i hold the source button it goes off and when i just press it it does nothing even pressing it and another button does nothing

 

i got it working dunno what i did maybe hitting a speed bump too fast but its working now
