I have a new 2005 Buick with a rear window heater/antenna. The heater
works and the FM reception is fine but the AM reception is terrible to
almost nil.. The dealer is working on the problem with the AM radio
reception and has ordered a new cable which they are going to install
when it arrives later this month. I doubt that this is the problem but
they think it is so we'll see after they install a new one. I'll post
a follow up when they figure out the problem with the AM radio. My
guess is that it is the radio but that is just my guess.

Hi all

Let me preamble this by saying I am new at this, and need your
help. But I am a quick learner!

I have a few specific questions and perhaps you can help. I am
trying to troubleshoot a Fm static problem

1) Is the car coax cable lead one or two wires? I am quite sure
it is two (one outer (the ground) and one inner wire) but I'll
ask to confirm

2) Should a "in-glass" rear winshield antenna be grounded to the
car's body? If so, from which end of the coax cable? (see Q 3)

3) Does the expression "grounding the antena" (in the case of a
glass mounted antenna) be as simple as soldering a grounding wire
from the outside coax lead end that plugs into the HU to a metal
ground of the car? Or should it be done closer to the actual
antena? SUch as at the junction of the end of the coax and where
the antenna starts...

Here is more detail on my problem if this helps: inconsistent FM
reception ( static) with in-glass antenna where I use to get
crystal clear reception with old car. However, there is a twist
to my problem: I noticed that the coax cable (inner cable) from
the HU is not truly connected to the antenna even if it looks
like it is. I tested it with a continuity tester and it is not.
When I try to connect the inner coax wire directly to the antenna
(using a wire and soldering), then I can test it and it is well
connected. In other words, the inner wire of the coax makes a
continuous circuit from the HU's to the end of the antenna. Yet,
I still get some static on some FM station (which is not induced
by the engine or the car's electrical systems).

Any suggestion? It is an RSX 2004 (Acura). I changed the HU twice
(two models) and the problem persists (same issue with the OEM)

TIA
