Likely you have amp and speaker issues

Send them to www.doctordons.com

if the CD & Tape yield good sound when in use then it's the CDM box that is at fault. That box has a pre-amp that appears to be working if the CD & Tape work. The box also has all the radio functions, and the radio's tuner.

Unless the antenna jack has come out of the CDM box, and / or lost it's ground back at the mast location then the tuner sounds like it's out to lunch.

The CDM box is up under the knee bolster on the passenger side of the car. You have to take down that carpet panel, take off the door to the fuse box, and unplug 5 or 7 harness connectors that cross under the bracket that holds the box in place. To remove it is a real pia, it helps to remove the passenger seat so you have room to work. The bracket that holds the CDM is a twp piece set up that is fairly flexible plastic. The box has 5 or 6 plugs and two 10mm nuts that hold it in place. We may have a write up here somewhere.

You know your Bose! Must have been under there not so long ago. I thought the antenna jack connects to the back of the head unit. Am I suffering from senility also?

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.

As has been said, antenna disconnected or the mast is not coming up.
The issue of not getting any radio stations is not related to amps since CD/tape work. (obvious)
IF amps start acting up the current wisdom is to replace them with the very inexpensive ones ($7) from a 95-98 Nissan Maxima rather than repair them. I've done it both ways.
