DO YOU GUYS KNOW IF U CAN TELL THE DIFFERENCE BETWEEN A REGULAR CD PLAYER AND THE MP3 PLAYER JUST BY LOOKING AT THE HARDWARE? I MIXED UP THE TWO AND CANT TELL WHICH ONE IS THE MP3 PLAYER OR THE CD PLAYER. ARE THERE ANY DIFFERENCES? PLEASE LEMME KNOW..VERY URGENT. THANK YOU

I don't know if this will help, but if you order the MP3 player from Canzoomer, the part number is GJ6B-79-AGXB and the associated panel is F151-79-BGX. If that is the actual Mazda stock number then perhaps it is also printed somewhere on the MP3 player itself.

On the bottom of my stock CD player is a sticker that says:

MODEL NO. 14787462
PART NO. F153 66 AG0
DC12 VOLTS NEGATIVE GROUND
