Yes, I did mine when I got my car, and just two yrs ago I did Lou's in his car.
I forgot to add that Dr. Don can repair the CDM box also....sorry about leaving that part out. I would check to see that the antenna lead is plugged in to the CDM before I went thru the trouble of actually removing it from the dash....that would be at the 1/2 way point in the removal process. I believe the antenna connection is on the right side of the box near the front(?) I think near the front of the box....sorry I can't remember exactly.

also fwiw if you have to pull the CDM box and your speakers have never been rebuilt I would send them along with the box to Dr. Don and have it all done because it's not "if" but when the speaker amps will blow the defective capacitors. You can call Dr. Don and talk with him about your particular issue and he will give you the straight scoop on what's best to do. Me, I eventually did the entire system in my car and it is just fine by me now.
