Been messing around with the Bose in the breaker today, trying to work out whats what. Previously if I put a CD in it would play ok, now I can see on the screen which track is playing and how far through the track etc, but no sound comes out of the speakers. There is a "hum" at the speakers, so seems like they are working ok, but no sound.
I also appear to have lost the radio stations from the memory since disconnecting the battery, and I dont seem to be able to retune to any stations. :-[ :(

Serves you right for messing around with stuff you know naff all about ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D ;D

Have you maybe blown something by trying to add an aftermarket head unit to BOSE despite virtually everybody on the forum advising against it ?
:-X

I think he`s blown his brains Dave stripping that car out :D ;D
-
No Dave, nothing like that. Just trying to find out if it all works ok, before I sell it - its from an elite Im breaking, and I have never so much as seen one before. It was ok two days ago, but not now.I have had the battery disconnected, and when I put it back the Bose cooling fan seemed to be running permanently, but nothing else was happening.I took the fuse out of the back of the headunit, and then put it back. This seemed to stop the fan from running, but still no sound or radio stations.the unit seems to be working otherwise. Its lit up and responds to commands from the buttons on the front, and steering wheel.
-
Is it still in the car, or have you got it rigged on a bench?

your not far wrong. ::) ;D

Check Fuse 12 and pin 7 on the back of the ncdc
-
ignore F12 - that would knock out the gid as well
-
Its still in the car. How do I know which is pin 7 ? :-[ ::)
-
Fuse 34, though doubt that will make a difference.
Daft Q, you haven't disconnected the Bose loom in drivers kick panel?
-
Havent touched the wiring in the kick panel - unless there is a bad connection there ? I have taken the panel off and the wiring is exposed, but I havent dismantled it in any way. :-/
-
Fuse 34 - one of the three big ones at the top ? if so they look ok. :y
-
have you had radio out?
-
well, its just free standing in the car as all the surround has gone. I have unplugged the plug at the back, but it has worked since then. :-/
-
Sound aside, does it work flawlessly?
-
You couldn't have dislodged the wiring under the parcel shelf could you?
-
Apart from no sound, I think its doing what it should, although I think the lack of radio stations is down to it losing the memory when I took the fuse out earlier.
I have taken the whole loom put from the parcel shelf today, took the amp out and brought it inside the car and then reconnected everything. I did this after the problem started, to see if there were any broken wires etc.
Dont suppose the amp has its own internal fuse ?
-
Just thought of something else (which probably wont help diagnose anything ::)) it was behaving in a similar fashion a few days ago. I was wrking around the rear of the car and all of a sudden the sound came back by itself and the CD started playing. :-/

Have you started to take this car apart yet?
If so the first thing you should have removed (after the electric front seats ::)) is the battery.
It's the only safe way to do it...
-
As I said earlier in the thread, the battery had been removed. It has now been put back on so that I can test the Bose system.
Its difficult to do that without a battery. ;) ::)
-
Ground connections? Cant remember if these are grounded locally, or via loom back to front of car
-
Sounds possible. Would it be an idea to attach a wire to the case and to ground, or would it have to come from inside the unit ?
-
Been having another fiddle with it todaY - checking connections etc. no joy though. Anyone know if the amp has an internal fuse?

Albs,I think an earlier post said the speakers were humming. That would point to power amp being on & working but no input signal - would it not ? :-/ :-/ :-/
-
I'd re-check all the connections - 36 Way ISO, Kickpanel connector, and Bose Connector. 0V is via the loom, not local to the boot area.
Another possibility is that you have a dead short or a short to ground on one of the speaker cables.

Have checked and rechecked the 36 way and kickpanel connector, cant see anything obviously amiss. Have checked rear speaker cables, but not the fronts yet. Dont know how I would check for a dead short ? :-/
-
I wouldn't have thought it would be possible but is the amp connector in correctly? One end has a hook arrangement that has to be hooked in before the plug will go in squarely. I'm clutching at straws now!
-
checked that. Took it out and reseated it to be sure. :(
Beginning to think ive knacked it somehow. :'(
Although, I also cant help thinking that in the process of removing various other electrical parts ive disturbed/ disconnected something to cause this. Although the syatem does mostly seem to be seperate from everything else. :-/
-
Problem solved. :) :)
-
Problem solved. :) :)
Do tell. Or are you embarrassed :D ::)
-
I had removed the retaining screws from the drivers door speaker. Seated speaker back properly in the door and put the 3 screws back, and hey presto. ::) ;D
Only remining problem is it doesnt want to tune into FM band, but thats probably me not knowing what Im doing, as everything seems to be connected properly, and it was ok on FM last week. Will have a fiddle with that later. :y
That will only leave possibly getting hold of an old satnav disc just to check thats all ok.

The Aerial plug on the flylead has probably fractured, common fault.
Just pop a length of wire into the centre pin of the aerial socket and route it out of the car for now. should prove the point. Don't forget that the original antenna dependant on saloon or estate has either a built in or external aerial amp to overcome the loses in the flylead.
-
sounds plausible, will have a look, thanks. :y
Btw - is it an easy fix ? :-/

Sorry to hack the post, but which way round is that?
-
The saloon has the ariel amp situated under the rear shelf. Dont know about the estate, if thats any help. :-/

Hmmm, in the Bose shelf? or is that not relevent in this case?
Only reason I ask, is that I use neither the GSM or Satnav, so was planning to replace the twig with an astra one, and remove the window ariel cable & fit to it, hopefully improving the 7 versions of heaPlease read the manual awful reception.
Then bugging DaveDND for a modulator that I can hardwire in- which he doesn't usually recommend due to the poor signal strength.
If there's an amp, that may queer it a little

Try pressing the mute button.....

Ok, that needs some clarification then.
An external aerial works better than an internal one - that we all know, and the internal aerial on the Omega has a booster in line as the signal is often so poorly received the head unit simply cannot sense it and any further joints or circuitry in-line with this poor signal may lead to the complete loss of radio reception - modulator will work fine, but radio reception would be significantly impaired.
Whether you want to use a wired modulator (no problems with that), or to improve the radio reception, my advice would always be the same - ditch the internal aerial and booster and fit an ordinary and decent antenna on the roof (from around £10) - For those of you making use of the extensive electronics, then Bosch and Hirschmann both do some excellent combined FM/GSM/GPS aerials that look identical to the standard one - prices anywhere around the £50 ~ £125 mark.
It makes me laugh to think that GM put an internal aerial with a booster inside the car to retain the sleek styling and cosmetic appearance of the car, and then thought, Oops! we still need another aerial on the roof for the phone, why they never combined it in the first place is beyond me.
;)

sorry to hijack this thread :P but question for dave
Bosch and Hirschmann both do some excellent combined FM/GSM/GPS aerials that look identical to the standard one - prices anywhere around the £50 ~ £125 mark
i have non-bosch ccrt 700 with phone to enable to use one of these combined aerials i would have to re-route the aerial cable to the roof??
if this is the case is the coax long enough to do this or would it need extending??
one other thing whereabouts would i purchase a combined aerial??
thanks

Not sure about cable lengths in the Omega, but we would always use new one piece cables where we could - 4.5m cables readily avilable on our website, and we can supply most types of adaptors where needed.
GSM cable should be long enough as goes to roof anyway.
As for the aerial itself, readily avialble from most "good" car audio shops, and I`ll have a shout about next week to see if I can source something suitable at a special "Oofers" price

Not in the Bose shelf were the amp is. It is bolted to the top of the metal shelf and is sandwiched between the metel shelf and the fibre board speaker shelf - if that makes sense ?

Checked the plug where it goes into the rear of the head unit, and checked the ariel connections at the rear screen and into the booster - everything appears ok. Tried the length of wire hanging out the window - didnt improve things - not sure what to do next. Still got awfule reception on FM whereas a week or so ago it was perfect. Probably disturbed something (else ) without realising. ::) :-/

What are you powering it up with, Albs? The original car battery? Any battery chargers, etc. connected?
-
Its all still in the car Kevin,with battery still in place. Having said that, the battery is getting low, so might give it a charge and then try again. ;)
Funny stuff electrickery. ::) :D
-
Yep, was thinking that a charger might well cause interference if you'd got it connected to "top-up" the battery. :-/

Nah .. your wrong ... cables contain compressed smoke, which is what electrickery travels in, it's not until the smoke escapes that the elecktrickery stops ... I've proved this many times .. when the smoke leaks out of a cable it stops working :y :y :y :y :y

yup .. electrickery only travels inside compressed smoke .. so all electronic thingie whatsits contain such smoke .. and when it escapes they stop working... seeemples :)
Be careful with that smoke mind .. its powerful stuff.... if too much escapes at the same time it gets very hot and can actually make other things that also contain compressed smoke leak as well... dead weird stuff that smoke ....
