That because you connected the wrong remote wire to the amps.The BLUE (only) wire is for the pwr anntena, that is the one is connected to your amps right now.
You just need to switch the blue wires,you have to connet the blue w/white strip to the amps.

Fm radio works fine but the dab will not find any stations, I have tried different aerials and still no good


What's the make & model of the radio?
Most DAB/FM radios work from the same antenna, so if you receive FM stations, you should receive DAB stations in your area.
It should be noted that DAB transmitters work on lower power than conventional FM transmitters, and so you may be in a weak reception area (for DAB). It should also be noted that DAB uses different frequencies than regular FM stations and household appliances such as laptops,WiFi, microwave ovens, etc can affect DAb reception.

Margaret, this is free public forum , demands don't play here (free)
and you double posted. why do that.? if you wish to elaborate
try posting below 1st post, as an add.
and for better help? why not post to a BMW forum. (faster)
and no car year, posted or car options listed.

Radio year, model and Car Cell phone options.

no matter.......
the first check on all electronics, is the fuse
most radios have 3 power sources, (to make all features work)
and fuses are on all 3.
have you tried all sources, AM/FM CD, MP3 USB (if opted) .
are all modes dead?
the next check is to try all buttons on the radio. ?
is there a mute button? if car has 4 speaker try the fader lever.
front to rear. left to right , still dead.?
cycle modes. radio, cassette, CD 6 pack , what ever, but do cycle them all as older cars the mode switch can stick.

The RDS is radio station text messages. for song titles.
including time, station identification and programme information.
if this part really works, the RDS part this means the radio is working, but the power amp is dead or muted.
try balance and fader.
many radios (1000s) have fuses in the radio for the speaker amp
that can blow. (shorted speaker wires a prime reason)
or some have in line fuse. and others are in the cars fuse box
which varies by maker or model year.

ok , im looking at the stock radio on level C stock 1991 radio
and even back when (stock to me) the is RADIO muting
so if your car has Cell phone muting bingo that.
and a fuse at rear of radio, (unstated purpose)
guessing,id say there is lamp that glows, CELL mute?


conclusion, no car year stated, or year radio of not origional.

I can't get the AM radio to find a signal. All other components work fine.


Hello
If you get FM radio stations, and only AM reception is immpossible, check whether AM loop antenna has connected to the respective poles at the back side. If it is connected, and still you do not get the Amplitude Modulation [AM] signals, check the input settings of the device is correct to recive AM. There will be a slelection option, for AM & FM. OK.

I have a 1999 Cadillac DeVille Concours with an AM/FM/Cassette/CD/RDS Radio. The AM works fine, the FM does not, screen shows digital info(stations like 99.3, etc) but no sound. RDS does not function at...


Hi there,

Well there's lots of possible reasons. The FM receiver portion of the radio is separate from the AM Band receiver, pre-amp, and amplifier sections of the radio. The FM receiver may have simply failed, as well as the CD player portion of the radio. Your car FM needs repair, you need a multimeter to check it or take it to a repair person. Please post further comments for further help or information......

Good Luck!!

Thanks

Reciever powers up and recieves signal (station and song titles are displayed) but doesn't transmit to car radio either through the assigned fm station or the aux cord.


IF you have a cord plugged into the audio jack, if will TURN OFF your FM transmitter. You have to leave it unplugged for the FM transmitter to work. Go to MENU and make sure your FM station is set and that the FM OUTput signal is turned up. Write back if you need more help.
Thanks,
John

There nay be a wiring issue with your amp. When you are running a CD more power and sound quality is envolved so the amp works harder. Check the amp make sure everything is where it should be.
