Problems with BOSE system in late model 156
I'm hoping someone here might have had a similar problem to this, so they can hopefully offer me a simple fix.
My Car: 2005 156 JTD (175bhp) with BOSE speakers and standard stereo.
The stereo doesn't turn off when the engine turns off, has to be turned off manually (maybe this is normal, I don't know).
When the stereo is turned on the volume is at about 20, and can not be heard at all. You have to turn it up to at least 52 for normal listening, surely this can't be normal. I'm not exagerating, you can't hear it even with the engine off at 20. It doesn't remember it's previous volume setting so I have to do this every time.
The CD changer scans for CDs and takes ages, yet even though there ar CDs in the magazine and you can hear the unit clicking as it loads them, they never play.
The sound quality is ok, but not as good as expected. I owned a Lexus IS200 and a Volvo S60 with standard stereos and both were much MUCH better.
Does the BOSE system include an amplifier, maybe this has stopped working which is meaning there is insufficient power in the system? Anyone any experiance of this? There seems to be an extra lead from the battery leading towards the back of the car that is wrapped in a blue sheeth (is this standard as it looks not to be).
Maybe the head unit has worn out, is there an aftermarket alternative that will work with the steering wheel controls and the cd changer? I'd also like a bluetooth handfree kit and sat nav would be great, though probably beyond my budget. I do have a philips stereo from my earlier model 156 twinspark, which included sat nav and a cd changer, which I had belived to be fitted at the factory, however I tried plugging it into this car and it doesn't work, so I guess the wiring is different (even though the connectors seems identical).
I hope someone can help, otherwise I'll have to take it to an auto-electrician and I have already spent hundreds on a new alternator, battery, tyres and service. Plus I could do with some new brakes as it accelerates quicker than it brakes and that is going to lead to disaster sooner or later.
