Greetings - my 2008 my bmw k1200lt radio show "no radio" sign and does not want to switch on. All fuses (including the one on the back of the radio) were checked and work fine.

Thanks for adding the year. My search was for a convertible and this particular search query makes it force the word 'convertible' in the search results. The only difference with yours is the roof, chassis don't change.

Where and what are the fuses radio BMW 325I 2008

hay un panel interno de fusibles en estos
buscar un panel de pl?stico extra?ble en las partes bajas de la rociada
fusible de la radio est? marcado claramente

there is an internal panel of fuses on these
look for a removable plastic panel on the lower parts of the dash
radio fuse is clearly marked

put 12 volts to it ? . no sign of life ck the fuse on it , if not give it back or trash it

Do you have NAV option? If not, you may be able to reset radio by removing all three fuses, one in glove box and others in rear panel right pass side, then put them back in, and this resets radio default which clears up issue in most cases. If you don't want to pull fuses, you can also disconnect battery, but be careful. With NAV, it gets more complicated. CeraCoat-NanoTech.com

there is a fuse in the back of the radio ,have you checked that one , if ok check that the radio is actually recieving power as may have a wiring connector fault

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.

Has the sat nav got power ? or is there no power to it, do any of the buttons work etc? It might just need resetting if so get back to me and I can tell you the details, please clarify?

BECAUSE THE RADIO IS DEFECTIVE, THERE IS NO OTHER EXPLANATION FOR THIS.

located in the fuse panel... which i'm told on bmw's is in the trunk... does your radio work
