I recently purchased a 2008 E91. The radio and chimes were working fine then they suddenly stopped working.

I have the following in the car

S663A Radio BMW Professional
S694A Provisions For BMW 6 CD Changer
S698A AreaCode 2 For DVD

Reading on here I checked for an amp in the boot and for other items under the boot carpet and I dont have either (I'm assuming they don't come with my spec) I also read about the MOST bus so I have found the connections in the boot, under the dashboard and in the back of the stereo (none are lit up) will these not be connected on my model?

I have checked the radio fuses in the glovebox and in the back of the stereo and they all are fine. I have also put my battery on a trickle charge incase it was low and was effecting the IBS. Is there anything else I can try before taking it to the garage? Thanks

Is Newcastle in the US or Europe?
Because all US cars between 06 and 2010 came with either option
676 or 677 both of which had amps .
In Europe or the Rest of the World you could have the ampless
base system which also has no tweeters in the most noticeable
in there absence from the front door sills.
If there are no devices on the Most Bus there is no need
for it to be turned on . I understand some Euro cars come like
this.

Apparently a lot of people build Newcastle's

Does the Radio Light up indicating power?
Do you have a voltmeter ?
If you do take it to a garage as you call it be sure
they do BMW's and ask them about your situation
because most places don't know how to work on a BMW.

If you want to diagnose and repair problems yourself
I suggest getting the Bimmergeeks cable and setting
up coding and diagnostic ability on a PC.

Thanks for replying.

Sorry it's Newcastle in Europe (UK)

No there is no display on the radio. I have a voltmeter although I am unsure how to test the radio with it.

Can I order a cable to be delivered to the UK?

Thanks

If you are in Europe you probably have a base radio did you check
for tweeters in the corner of the front door sills.
If you have no options such as bluetooth phone , Sos , Sat radio
or DAB you might have a radio or idrive in which there is no
need for a Most Bus and its turned off at the Head Unit or some
cases they have radio's that don't even have the Most Bus built
into the Radio.

You will have to talk to Bimmergeeks.net about shipping options
you probably can get a K/Dcan cable locally just look on ebay or
the UK sub forum here. The bimmergeeks cable is favored for quality
and reliability.

Check for 12 volts at pin 15 (see above pin out)
Your original conclusion that the IBS is messing with you may be
right.
If the radio is not lighting up there is no point in condisdering
anything on the Most Bus which you may not have anyway.

If you get a cable you can read the Rad2 file for the parameter
Ring Status aktiv or nicht aktiv. Which means most bus on or off.

if his car has cd-changer preparation then radio will be with MOST
check radio fuse, get replacement radio from ebay.co.uk and code it in some indy shop

Thanks. I've ordered a k/dcan cable. No tweeters and I have found the most bus wires but I thought it must be turned off as in the boot the wire is not connected to anything so therefore not creating a circuit. Is it still worth checking the voltage at the head unit or will I need a replacement?

[ctuna]

Alway's better to measure things for a Sanity
check.
You could also bench test the Radio with a 12 Volt source.

They pre wired cars in the US from 06 to 09 in this series.
doesn't mean anything is hooked up to the wiring though.

this is cd-changer prepartion, but it is disconnected from main loop now
check voltage, replace fuse and if that would not help - get replacement headunit

[SteFos]

Thanks for all your help. I ordered a k+dcan cable and new head unit and it is now working fine. Could somebody point me in the direction of software to use with the cable please.
