I'd be interested in that. How much you asking? I asked local GM dealer what the part number was and they said 9390772. That was for 94-99 Bonne. Does anyone know if units for Grand Prix are the same? I have HUD and Steer wheel controls. Do most of the units have connections for these? I've seen the #16213372 that is a Delco model number, but the GM parts guy had no listing for that.

You have a PM.

I PM'd you back.

I just bought my 1999 Pontiac Bonneville and the radio does not work but the CD works great. Sound is fantastic? Any idea where the problem could be from the unit to the antenna?

By the way this car had one previous owner and 81,000 original miles. Car is sweet!

I don't know why it is not working. Have you asked the previous owner what the problem may be? I would post your question under a new topic in this forum under the "Audio" area. Members are extremely knowledgeable and helpful. If you can't get it to work, I have one I could sell you. It is the HU with the Bass and Treble slider. Good luck.
