I have had both TNNs for the interference and whining noise issues but I still have lots of interference regardless if it's a clear or cloudy day.<p>I am assuming it has something to do with the AM antenna connections since it gets worse (or better) if I hit a bump or pothole. Some times it even gets better when I hit the brakes or turn in a different direction.<p> I do listen to a lower AM station but it gets really annoying since I took care of the TNN on my own dime after my warranty expired and it still is not the way it should be.<BR><BR>

Re: Location of AM antenna and wiring? (pie_ya)

Found this on the net: One antenna is in the rear bumper, check that the connector is plugged in at the right hand side of the car in the luggage compartment below the light cluster. The second arial is integrated into the rear window and is connected to a module on the left hand of the vehicle behind the C piller trim.<p>Which TNN's, specifically did you have performed? 39-35?

Re: Location of AM antenna and wiring? (pie_ya)

Here's what I found. Unfortunately the pictures don't work, and I can't find a .PDF with working pics. Maybe this would solve the problem?<p><b>Audio System - Poor AM Reception<br>NO: 39-35<br>DATE: 04/03/2003<br>MODEL/YEAR:<br>S80 MY 99 ->, S60 MY 01 -><br>SUBJECT:<br>Poor AM Reception<br>CHASSIS:<p>REFERENCE:<br>Service Bulletin 39-0018 and 39-0025<p>DESCRIPTION:<br>Cases have been reported in which AM static will increase and maintain a higher level resulting in complaints of poor AM reception. The increase in AM static may be triggered by several reasons including: bumps in the road closing the doors. The AM static will stop by several reasons including:<br>Central Door Lock activation rear defrost activation touching the trim covering the antenna amplifier.<br>SERVICE:<br>It has been determine the increase in AM static is due to a loose connection between the antenna amplifier and antenna cable. To improve the connection (and AM reception) this Tech Net Note provides instructions to install a brass strip Part Number 30657370.<p>The brass strip must be bent as shown.<br>NOTE: It is critical not to exceed the 8 mm (5/16") length. If this length is exceeded it will result is worse reception.<p><br>Install the brass strip into the antenna amplifier as shown.<br>Install antenna cable so that the locking clips are not on top of the brass strip. It may help to push the locking clips to help seat properly.<br>NOTE: After the antenna cable has been installed pull the antenna cable to verity the locking clips are holding the antenna cable in the proper position. If the antenna cable releases easily the locking clips were not seated.<p>Picture of antenna amplifier after brass strip has been installed.</b>

Re: Location of AM antenna and wiring? (Jexx)

I think 39-35 is the fix I need because I tried turning on the rear defroster on the way to work this morning when it went all static and it fixed the problem.<p>Thanks for the TNN as I didn't see it before. I can't believe that there are three TNNs for this stupid radio for almost the exact same thing.
