You need to get the radio code which will cost you, Search for radio codes online or call the dealer. The dealer will not give you the code intil you can prove you own the car but since this is a replacement from another vehicle someone will need the model and serial number of the radio.
I personally would of had a aftermarket one installed. It would of saved you alot of aggravation.

The radio will have to be removed from the dashboard.

Then post the radio make+model plus all the letters+numbers on any labels,barcodes or engraved in the metal casing.
