How to filter out the FM radio static on the Garmin Nuvi 6xx

What am I doing wrong? How can I filter static out of the Nuvi 6xx FM
transmitter? Where is the static coming from anyway?

I find it hard to believe the Nuvi is transmitting the static so may I ask
where the static is coming from?

Since the Nuvi is only a few feet from the antenna (in my case, the antenna
is hidden somewhere in the car because there's nothing sticking up
anywhere) why is there so much static?

Is there a way to put a filter on the static? I tried every station I could
but to no avail.

What is the best way to get the Nuvi to play on the radio WITHOUT all that
annoying static?

Hi Sharon,
I had/have the same problem with my XM radio. I thought I it had a
weak transmitter. But I learned it was only a problem in big cities
where it seemed like all the radio frequencies are filled. For some
reason, I had better luck setting the transmitter to a higher
frequency (i.e. 107.1). My XM radio also has a transmitter power
setting. Check that if you have it.

I hope this helps!

The Garmin nuvi I have has a very weak FM transmitter and won't transmit
on all freqs. I have several where there is no signal but it won't tune
there -- it just skips over many frequencies while being tuned. I
thought it was me but when I went back, it truly skipped the ones I most
wanted to use. I have to make do with some noisy ones and keep shifting
as I move around. It is very irritating!

The source of static has to be found by a process of elimination. With the
power adapter plugged in and on, turn off the GPS unit and remove it from
its holder.
If the interference is still there you have a faulty power adapter. If the
static goes away it must be the GPS unit that is at fault.
With properly functioning power adapters and GPS units no further user
installed filters should be necessary. However check that FM reception is as
good as it has been without any of the Nuvi parts active. It is just
possible that the earth shielding or antenna connection of the radio is
faulty.

Park your car. Put the ignition in the ACC position and fire up the
nuvi and your FM radio. If the noise is there then, play with the "what
frequency the nuvi is transmitting on" option on the nuvi until you find
a frequency that is static free. You'll have to re tune your FM
receiver each time you change the transmit frequency on the nuvi.

If the nuvi does not allow you to change frequencies it is a poorly
designed unit. If it does it all by itself without any input from you,
it is a poor implementation.

Garmin may have presumed that nuvi buyers will be technically inept and
unable to work things like this out for themselves. If you don't fit
that model, you may have bought the wrong GPS receiver. You're not a
trouble maker are you?

Anyway, once you get it on a quite static free frequency you can start
the engine. If it remains static free, start driving. If the static
comes back intermittently as you drive, it may be caused by localized
changes in the radio frequency spectrum. You have to either live with
that or you can pull over and look for another quiet frequency.

Let us know how it work out.
