Does anyone know the radio code for a 99 eclipse gs ? or can someone give me the number to call?

Go to the dealership........

If you pull the radio out the code should be on the side of it somewhere.

radio codes are not printed on the side of the radio. Its a theft detterent. Let me help you by giving me the serial # of your radio, and i'll post it back to you......[8D] (need to take out wrap around panel so you can scope or take the radio out.....:)
