Radio - Interference/Noise On AM Band

My 2001 S80 HU-611 radio has worked perfectly on AM and FM and cassette
tapes and with its built-in CD player as well as the trunk mounted 10-disc
stacker since I bought it October of 2001.

Now, within the past 5 days it has begun to make a lot of noise on AM only.

I'm loathe to monkey with it myself. I wouldn't want to try to take it out
of the dash because I'm positive something would break - like it did when I
tried to change my "dipped" RH headlight bulb the other day. Besides that I
hear it's protected by some kind of electronic code that would have to be
reset in some mysterious way.

But it seems likely that the built-in antenna may have loosened up somehow.
Or maybe it's something else.

Whatever it is, it's starting to piss me off. Any ideas? Easy to fix?

This is a common problem on S80s. Volvo has several bulletins on this,
with a multitude of fixes, including rear seat grounds and signal wires
from electrical modules. If your warranty is still valid, it may be
worth going to the dealer.

I saved this post from G Klein:

There is a fix for this problem yon have to remove the Left rear C-Post
cover there you will see the antennae cable where it goes in to the
signal amp use a razor blade remove a small amount of insulation from
the radio connector you will need a length of wire to connect from the
antennae cable to the body ground just below the antennae cable usually
this solves most of your problems

Replace tt with t (twice!) and remove parentheses to email me directly.
(But I check the newsgroup more often than this email address.)

 

Volvos new correction is to place a small brass strip in-between the ant amp
& the cable make a slight bend toward the amp hold in place with a small
piece of tape If you like I will retrieve the information from the Volvo
service web site & if anyone would like a copy just post a way to receive &
I will send to all who ask

We just took delivery of a 99 S80, and we're finding both AM & FM go
to nothing but static whenever we turn on the rear window defogger.
Will the antenna fix solve this problem, or is it something else
entirely?

Thanks

 

It sounds like you have a loose connection @ the Left rear C-Post where the
connections are made @ the rear glass
