No Power on Radio: Help

90SLOWE · 07-14-2012, 01:17 PM

I turned on my car yesterday and I have no power on my radio. I do get the sound warning for the passenger seatbelt / open doors.. etc so the spearkers work but I have no power on the radio/cd player console. The display on the console also does not work. I tried all other electronics including the AC and AC display, they all work fine.

I read a couple other posts about this problem but could not find a solution. Please help.

2006 E90 330i, no iDrive

Check to see if your battery is OK especially if you have and 06 or 07

Read the article above for info on how the electrical system and ibs works.

Yes the problem was fixed, I disconnected the battery, waited for about 1min and reconnected it. That solved the problem

I've been fighting this since early this year.

I don't consider disconnecting the battery as a fix. Have you found a permanent solution?

I actually ran across your post when I was searching for a solution for mine. However, mine was different because for the time it went off, it never came back on. I checked the fuses, tried disconnecting the radio, but it did not come back on. However, disconnecting the battery did work for me and fixed my problem. It has worked perfectly since then.

Have you checked your fuse? One of mine was placed wrong too which I corrected. Maybe that was what initially caused the problem

When you say your fuse was placed wrong what do you mean? Wrong value? Or not seated correctly?

I still see this issue recurring and I somehow doubt it's a fuse since resetting the radio by disconnecting / reconnecting the battery always works for me.

My sense is that it is a turn on voltage transient issue and could be either the radio or the battery. I suspect the radio since my car is a 2009 and the battery should have another couple of good years.

It was a wrong value (30 instead of 20 on slot 31).. i'm only guessing that could have caused it on mine. I do not have any technical knowledge of the electronics in the car

2010 320d Non iDrive, No Radio Display(no power tried holing menu for 10 sec n all), PDC is also off, steering mounted control also not working. AC unit and other functions are working. Tried battery connector removing for a while. Check fuses too but does not seems working. Any body has face similar issue of Radio Display, PDC and steering wheel control not working ?

Battery's last an average or 6 years in these .
The IBS system can cause all kinds of unrelated problems
when the battery is low.

Thank you for your reply, last year only have replaced battery

ctuna · 02-13-2018, 02:48 PM

Doesn't mean you shouldn't check it.

christianarpan · 02-14-2018, 10:26 AM

yeap will also again double check battery now. do let me know if have any other thing to check. Without audio system, drive is really boring..

christianarpan · 02-19-2018, 09:48 AM

I check battery even again try with remove battery terminal and reconnect after one mins but no luck

ptpending · 02-19-2018, 01:17 PM

you can bus is damaged in some way and so some units cannot communicate
therefore radio is not activating without can bus

christianarpan · 03-01-2018, 01:13 AM

Thank ptpending for your reply. Can you guide me how to check 'can bus'.
I removed Audio system (Alpine Model C73, P/No. 65.12-9 205 962, e24) and on back of sound system there is 10 amp fuse, checked conductivity its fine.
Also try to check voltage on sound system connector but no power.
kindly guide me further. Thank you..

ptpending · 03-01-2018, 06:04 AM

ok then you need to check 14, 15, 18, 19, 27,42,56,63 fuses

christianarpan · 03-07-2018, 04:05 AM

I have checked fuse. only fuse in 14, 19 and 63. All conductivity okay and even showing voltage aswell. 15,18,27,42,56 are empty. If get it scan will it help to identify issue. pl guide me further. Thanks

christianarpan · 03-09-2018, 04:18 AM

I went to local shop, they check everything. there was something wrong in power supply in audio system, took almost $100.00 and got it fixed. Finally its working Thank God..
That technician told from side panel of audio, led light will be visible. if thats not working then something wrong with radio system itself.

chendrix14 · 08-31-2018, 08:49 PM

Hey Christian,

I have the same issue you have described. Can you elaborate on what the mechanic did you get your radio working again?

I have no LCD display or power at the radio and no optical lighting at any components i.e. radio, satellite amplifier, etc.

jarrod_hickman · 08-27-2019, 08:45 AM

i'm having the same exact problem after i installed my second line out converter for my amp. anyone know what could be going on? my backlit buttons come on but the screen is totally blank

ctuna · 08-27-2019, 11:50 AM

Step one there is either power to the Radio or not
Radio has a fuse on the back and one in the cabin fuse panel.
If you have a low battery the IBS may be turning off power
to the Radio.
If you have done the above checks and there is power on the
Radio connector and it doesn't turn on then its the radio.

IBS system can turn accessory's such as the Radio off if it
detects a low battery or is defective.
