I replaced my factory radio with one from a junkyard but lost the code.
I have no way of knowing the vin. When I pulled the radio the only identification tag that I can see is a small white one on the back (PPE0022851). Not sure if that is a serial number or if I have the slightest chance at getting this radio to work again...

 

Do you know the dealer where you got the code? Pretty sure they need the VIN to get the code, but call them and see if the serial # is enough.
