Hi all

Is there anyone around the Surrey are who fancies (paid) a look at my bmw business audio system - (2001 330d Estate)

Immediate problems -

* 6 cd Changer was working but recently says "no discs"

* Bought Aux input kit, connected it, but AUX doesnt show as an input in options.

then..

* Want to connect a sub, I have one and amp.

* Upgrade the system

* Possibly replace head unit with a later one.

Can anyone help?

Thanks !

For the first two try disconnecting the battery for 20 mins, this will reset the various modules except the security ones.

When installing the AUX port did you unplug the lead for the disc changer and forget to plug it back in?

Thanks Mike !

The CD changer stopped working before I touched anything :-)

Will disconnecting the battery upset anything else, like the alarm / keyfob etc? will all work when I reconnect again?

Thanks !

Disconnecting the battery will not effect the alarm central locking etc.

All it will do is reset all the non critical ecu's and modules.

Everything will still work once reconnected, and hopefully the changer and aux port

The changer has a fuse in the back of it, it may also be worth taking the unit out and checking that as well

Hi Mike

Thanks for this!

I removed the earth on the battery for about an hour. It solved the CD problem, at least I can play CDs now. Still no AUX input though, not too urgent though, at least I have CDs again now !

New question-

Will later head units work with my 6 CD changer?

Not sure about newer head units.

If it's a BMW one then it possibly will but the main plug on the back of radio will probably be different.

I think your radio plug has round pins where as the newer ones have flat pins, it may be possible to get a patch lead to connect the two different types
