Hi having a problem with the Bose system in a 2003 Vauxhall Omega Estate.
The system plays fine then the sound will just disappear but the CD continues to play.
The sound can be gone for various lengths of time.
I have got a spare used amplifier but this has made no change.
It kind of points to a faulty headunit but wanted to see if anyone had come across this problem

Thanks

sounds like it could be the amp is getting to hot, is there room at the back of the unit?

Sounds like a tired laser to me, are you using CD-R's in the changer?

[TheBoy]

Does it do it on all sources - eg tuner AND CDC?

If so, the fault is usually the rear board at the top of the NCDC unit.

NCDC unit ??

[twiglet]

NCDC is the model of head unit fitted to the later Omega's with built in Sat Nav. EG, NCDC2013 or NCDC2015.

If you don't have sat nav, you probably have a CCR2006 headunit fitted.  Radio/Tape/4 CD Changer...

[TheBoy]

Ah, yes, it may have a CCR2006. Let me pop the top off one, see the board layout...

Got some spare

He did have a spare rear board,but I had it. ...............its possible he has a collection though.

  It's a NCDC 2013 unit. We replaced it with an Alpine to give him Bluetooth and iPod control. Another query is it possible to keep the fuel consumption reading etc now the factory unit has been removed ??

Thanks

Your loss of audio is probably the BOSE amp shutting down by overdriving it with a non-compatable Alpine head unit.

1) Bad idea, that Alpine unit won't last with Bose speakers, loom and Amp. It will go bang very soon 

2) No.

[albitz]

Other way round surely ? 

[Dave DND]

Other way round surely ? 

The Alpine will overdrive the BOSE amp causing a failure of the amp, which in turn may emit a faulty square wave output which will destroy the speakers - meanwhile the Alpine head will now see the blown amp as a short circuit, and will then fry the internal amplifier IC.

Bottom line, its all going to end in tears.
