Hello -

I apologize... The best we can do is provide a wiring diagram of your system. They have not released any information on troubleshooting the radio system.

The light being out is probably due to one of the bulbs on the circuit board being burnt out. Many of these have to be replaced by a radio shop as they are extremely small and are soldered in.

Once in a great while there may be one bulb that is in the base bottom or back of the unit that provides lighting when the lights are turned on. You can find this out by talking with the parts department and seeing if there is a bulb on the unit.

Since you just got if from the dealer, my suggestion is to take it back and have them troubleshoot and provide you an estimate.

Would you like a copy of the wiring diagram?

Hello -

Here is the diagram. . ...so you are able to see it I had to crop into sections so just print and put together.

Also, the estimate at the dealer is good, but also I would check some radio shops and other foreign car repair shops. That way you have a good variety to choose from.

Hello -

Thanks for the update. Again, you still might consider talking to a few auto radio shops. Some of them can remove the radio and change out the bulbs...
