Question about JVC KD-S890 CD Player
The fm radio frequency search my JVC KD S890 moves in steps of 0.2 MHz leading to reception of only odd numbered stations.
Any idea how to movw the frequency in steps of 0.1 MHz?
I have a car stereo purchased from the US and I can’t pick up all radio stations in Europe/UK, what can I do?
If you have purchased a car stereo from the US you will find that it will not pick up many European radio stations. This is due to the fact that US radio frequency steps are different to here in Europe.
You may be able to set the tuner to European stations by following this procedure.
Press and hold down the SRC button to power down the unit completely.
While the unit is off press button 1 & 5 together, while momentarily pressing the SRC button.
If this does not work try the following proceedure;
Press and hold buttons 1 and 5 together, while momentarily pressing the reset button.
If this does not work then the unit is not designed to pick up European frequency steps.

SOURCE: tuning station problem
To change the channel spacing from 0.2 to 0.1; hold the FM button for approximately 2 seconds, then while still holding the FM button, press and hold the #5 button. The screen will flash with either US for 0.2 spacing or 01. for EU (Europe) spacing. Press any other button to exit. (I have done this with mine and it works).

I was having the same problem with a jvc kd hdr 30. I Installed it myself over a year ago and never wanted to deal with the issue. Finally, I decided to take a look at it today.
On my head unit, all wires were connected except one blue one with a tag that says "do not connect to power, for remote device or power antenna only." This unit is in a '97' MBZ E320 with no visible antenna; I think it is part of the windshield. In any case, between the wiring diagram in the manual and the harness that is part of my car, I was left with 2 blue wires to choose from, one with a white stripe and one with a gray stripe. After testing both for power or ground, I determined neither had power with key on or off. Both had high resistance ground when compared to the chassis ground. In other words, I measured between chassis and these wires. First, I took a wire and connected it to the chassis ground and connected the other end to the blue wire coming from the unit while tuned to a local am station. This simply killed all reception am or fm but did not harm the unit. Next, I connected the blue wire with gray stripe of the car harness to the blue wire of the unit and again this killed all reception. Then I connected the blue wire with white stripe of car harness to the blue wire of unit and presto magic I had great am reception.
I am guessing that this blue wire with white stripe must be part of the antenna itself or perhaps is a connection that increases antenna power. Maybe 'power antenna' on tag refers to an actual powered antenna (like as in amplified?) and not as in an antenna that rises up out of fender, as I believed.
This may not help the first person with the question, but maybe it will help someone out there who searches for these kinds of answers like I do from time to time.

u should set the fm frequency on your modulator as same as ur car radio. example, if ur radio states 100.00, set ur modulator 100.00 also.

Using the tuner
Listening to the radio
The following steps show you how to tune in to FM and
AM radio broadcasts using the automatic (search) and
manual (step) tuning functions. If you already know the
frequency of the station you want, see Tuning directly to a
station below. Once you are tuned to a station you can
memorize the frequency for recall later-see Saving
station presets below for more on how to do this.
1 Press the FM/AM button to select the tuner.
2 Use the FM/AM button to change the band (FM or
AM), if necessary.
Each press switches the band between FM and AM.
3 Tune to a station.
There are three ways to do this:
To search for stations in the currently selected band,
press and hold TUNE ?©/?? for about a second. The
receiver will start searching for the next station,
stopping when it has found one. Repeat to search for
To change the frequency one step at a time, press
High speed tuning
Press and hold TUNE ?©/?? for high speed tuning.
Release the button at the frequency you want.
Improving FM stereo sound
If the TUNED or STEREO indicators don't light when
tuning to an FM station because the signal is weak, press
the MPX button to switch the receiver into mono
reception mode. This should improve the sound quality
and allow you to enjoy the broadcast.
Using Neural THX
This feature uses Neural Surround™, THX® technology to
achieve optimal surround sound from FM radio.
• While listening to FM radio, press AUTO/DIRECT for
Neural THX listening.
