There must be some way to tune my 2002 BMW 525 radio to a particular FM
frequency but I can't figure out how so my GPS won't work.

My Garmin GPS nuvi transmit on any FM frequency I tell it to. The
instructions say find an unused frequency and tune the radio to that
frequency. OK. But how do you tune a BMW automobile radio to an unused
frequency?

On a friend's car in a parking lot with everything turned off, I can tune
his American car radio to any FM frequency I like ...... for example to
100.1 FM. Then I can set the Garmin nuvi to speak on 100.1. There's a whole
lot of hissing and other sounds but at least I can hear the music and
driving instructions through the American car radio.

However, on my Beemer, there are only two settings. One will only find
"working" stations so it skips right past the weak GPS FM transmitter
signal. If I press the little BMW "m" on the stock radio, I can then press
the arrow buttons to go back and forth a bit, but still, there is no way to
get to 100.1 which is the cleanest empty station in my area. The dastardly
BMW radio skips to whatever station it wants to when you press the arrow.

I'm frustrated with the BMW radio lack of tuning ability.

How do we tune a BMW automobile radio to an unused FM frequency like 100.1?

I would pick one of the empty (skipped) FM broadcast stations. I would
then set the GPS to output on a skipped broadcast frequency, eg 100.1
and then let the FM radio "find" your Garmin. If possible, get the
Germin as close to the auto antenna as possible.

According to my E39 radio manual (have one? looked at it?), you select
manual (the "m" button in the middle of the radio/cd track seek and then
press the left/right buttons to the appropriate freq.

You press the M button to change it from "seek" mode to manual tuning mode,
then you use the right/left buttons to set the frequency. This is detailed
in your owner's manual.

Press the M button and then tune manually - works on my Bimmer (E46) and my

It tunes like the radio used in any other modern car. You can use
either a signal seeking scan to the nearest strong station or tune
manually with fixed increments between channels on LW, MW and FM.

There are no modern automobile receivers with analog tuning that I'm
aware of so you are stuck with fixed increments like 9 or 10khz on
MW, etc.

Set the tuner to manual then advance one channel at a time to a
relatively empty one. The owners manual for the radio should have all
this.

That's my whole point. When I press the "m" button and then press the
arrow, the radio STILL moves to the next "used" channel. It will NOT move
by a tenth of a point at a time.

Are you telling me that's how it is SUPPOSED to work? I would have thought
so too, so please confirm.

Maybe my radio is broken because whether or not I press the "m" button and
then press the arrow keys, my BMW radio STILl skips to the next used
station!

Drat!

OK. I guess my radio's broken then 'cuz when I press the "m", I still can't
get to any specific UNUSED station like 100.1 FM. I can get to plenty of
used stations, but, not to unused stations. Sigh.

Sigh. My "m" doesn't work then. There is no way, no matter WHICH buttons I
press, to get to an unused station on my BMW radio. I guess it's broke.

Just went out to double check both car and bike - and the m button cycles
manual tuning on and off as everyone says. As I'm in the US, it will only
tune to "odd" frequencies, 100.1, 100.3, etc., so is it possible your radio
was set up for another country?

Hope you can get it resolved.

Aha! Now we're getting closer! In your case, it skips every other tenth. In
my case it skips to the next USED station (with or without the 'm'). In
everyone elses' case, it goes to every tenth.

How wierd!

I'm betting you're holding down the tuning button to make it go a long
way across the dial to get to 100.1. On most radios with tuning buttons,
holding down the tuning button for more than a second makes the radio
scan. Try pushing and immediately releasing the tuning button several
times; see if it will change frequencies by 0.2 every time.

In the US, FM radio frequencies are always on an odd tenth, so many radios
will only tune to odd tenths on FM. In my experience, most FM radios behave
that way.

Another possibility is that the "m" button is the problem. If it isn't
working, then the scan button will either scan or advance to the next
preset.

If so you will find that the digital or vari-cap tuners or rather stations in
the US will be 9Khz apart and the Euro stations are 10Khz. This makes preset
and seek tuning difficult so they make the auto-tune radios for different
markets similar to cell phones.

If your tuner jumps 9Khz then you are NEVER going to get 100.1. However if you

US FM broadcast channels are 200kHz apart.

US AM broadcast channels are 10kHz apart.

After a lot of use, some push buttons on radios (and some other
electronic thingys too, such as tv remotes) will stop working because
the electronic contacts under the buttons wear out/lose good
contact.Might be your radio has a reset button, only guessing at that.I
once bought a Sangean AM/FM/Shortwave radio from www.ccrane.com
company.Under the battery compartment there was two little bitty
switches to set for American and Foreign radio statione.Even or odd
number radio frequencies.

Many years ago, radios were optional equipment for cars/trucks in
America.So were heaters and wind shield wipers too.When I was in the
Army at Scott Air Force Base,Illinois in 1963, I bought a 1958 BMW
Isetta car ($350.00) from an Air Force Officer.One door, (the front end
of the car was the door) one cylinder air cooled 9 horsepower engine,
chain drive to the rear wheels.I kind of wish I had kept that little
car.I still have the owners/operators manual to that car.A woman in
Germany was the first owner of that car.

By pressing M that should disable the scan feature. Pressing the
arrow button one should move the frequency display one increment only,
i.e. 970 to 980 but that is all. You have to push it each time to
move the display ahead one increment. It won't automatically tune to
an empty frequency or channel.

I was thinking along the same lines, but a lot of cheaper decks I've
seen (as well as the stock one in my '03 MPV) will seek by default, or
go manual if you hold down the tuning button for more than a second -
ie. press it briefly, it will go to the next available station; hold it
down, and it will stop as soon as you release it and operate in "manual"
tuning until you leave it alone for 10-15 seconds.

Most old car radios i fooled with tuned the coils instead of
the capacitors. The tuning mechanism moved ferrite slugs in and out of
the coils, while the caps were fixed. Less hassles with failures from
dust that way.

> Just coz its new don't mean it better.

If it's new it's built more cheaply. The old radios were
full of moving parts assembled by hand and components soldered
together by hand. lots of labour. When digital electronics came up
with synthesized tuning, it al came down to a few microchips installed
on a board, and a few switches, often soldered to the same board, and
all of it done by robotic machinery. The insides of those chips and
the displays are all made using photographic techniques. The whole
thing is probably assembled without anyone touching it. Translates
into inexpensive, but because it looks hi-tech they can charge more
for it. If they were to go back to building the old radios, we
couldn't afford them.
Some of those old car radios would pull in stations from
terrific distances. The new ones I've had get faint as soon as I get
out of sight of the station.

Some car radios has local/ "DX" button.
If you scan in local mode you don't get the weak stations like the Garmin FM

Marian, someone had your solution about 20 posts back:

1. Put the transmitter on the desired channel, and place it near the antenna
so the radio will find the new channel.

2. Use the scan feature that your radio seems to be stuck on, and let the
radio find the transmitter.

3. Once you find a frequency that is clear and usable, lock it in as a
preset on the radio.

Read the fucking manual of the radio.
First you'd switch it NON-RDS then depressing the search button for 3 or 4
sec. It should enter in manual mode. Searching again should allow you to
tune it on any frequency. If the Nuvi delivers a strong signal, it will damp
the radio signal itself.
I'm currently using this feature with an FM transmitter I bought on e-bay
coupled to my Archos 504 to listen to MP3s.

But again the procedure depends on the radio.

Didn't the OP say he had pushed the "m" button like the rest of us had

I think that the 300 series was the beginning of the end of BMWs as
"pure" driver's cars.

I suppose the sign that they were finished with that market was when
they dropped the "Ultimate Driving Machine" slogan.
