Press F1 and F6 on the radio and hold it when the car is on... then press the VOLUME SEL in when you highlight a * code, then write all the codes down and put them up here... then clear the codes, and re-do the steps and write THOSE codes down. Let us know what they are.

Codes will look like P2500C, P0128H, etc
