Hi, first technical post, please be gentle. I am getting an Omega Elite with the Bose system and have seen a few posts saying that the headunit cant be changed because it needs line outputs.
Could this solve the problem?

nope.
If you want different HU, lose the bose amp and bose speakers

No, although the BOSE amp is using line level inputs, the actual voltages are unique to the BOSE system, and nothing aftermarket will run correctly with it.
To make matters worse, the BOSE speakers in the car are 2 Ohms impedance instead of the more conventional 4 Ohms ones, so must also be replaced if running anything aftermarket

Thanks for the replies, bit of a bummer as I wanted to connect my iPod, oh well back to the drawing board.

One thing to bear in mind is that the Bose loom is still useful if your ok with a soldering iron as it takes a remote switch on, 12V, 0V, line out and speaker feeds from front to rear / rear to front.
Can save you a bit of time but needs some tweaking at the HU and Amp ends for the correct connectors. I think the +12V is about 20A so make sure the Amp doesn't require too much power.

Cheers guys, I have tried the fm route before , so think I will try the cassette adaptor from Sony. Only eight pounds so nothing ventured and all that.
-
Some cassette adapters are poor, even supposedly 'quality' ones. Yet I have a real cheap, nasty one, must be 10-15yrs old, and its superb (for my tone deaf ears). Trouble is, I dont have a cassette player ;D - which pleased Mrs TheBoy, as she's now nicked it for her car ;D
-
Lol, sounds just like my wife, except it is my pockets that get rifled for "change". I can't go wrong for 8 pounds, if it is crap so be it.

Of course it will be rubbish, look who put their name on it ;)

Remember NEVER to use one of the tape adaptors on a electronically assisted cassette loading mechanism, as it can cause severe stress to the mechanics due to the fly lead causing an obstruction.
If you have the older style cassette deck that need to to depress a button to manually and mechanically eject the tape, then you should be fine with these.

The (naff) R770 in her Rover is mechanical. Seem to recall the CCR600 and CCRT700 are as well.
But the el-cheapo cassette adapter worked a treat in my trusty old 18yr old Kenwood, that is most definately soft touch. I love that headunit, shame the '2' button has dropped off now (but it is really old)

I`m not saying the adaptors don`t work, far from it, but when you come to eject the tape, if it jams, as they often do, a mechanical one will require so much force that you will stop pressing the button and have a look at it, whereas the electronic ones will keep trying until the gears have stripped on the loading mech.

Ah, getcha :y
My cheapo - the best I've ever used :o - the wire comes out on the corner of the top and the side you see when inserted, so it only really goes in one way, and only in decks where the heads are on right (I think, from memory). Never had it get caught :)

Hi Guys. Just sharing that I've actually upgraded my stock HU (CCR 2006) to a Kenwood (IPOD and USB ready) 2din and it works very well with the Bose Amp and Speakers. It was just a straightforward swap with with you still being able to control the balance (L-R) and fade (F-R) of the speakers. The drawback is that you still can't control the bose subs from the HU as the Bose system is an integrated Front Channel, Rear Channel and Sub Channel. Hope this helps

It will sound below par, the volume is less controlable, and you may well eventually smoke the HU.

Agreed - you are certainly overdriving the BOSE amp, and something will go bang, often in a very expensive way.

I'll bear this in mind. Although I don't think I'll smoke the HU since all it will ever do is give signal to the amp via the speaker lines. As for the volume control, it seems the same. But I can only speak for my installation and I could be wrong. I'll definitely let you guys know if things go south on the HU.

The original head unit was around 8 Watts per channel and had a very narrow "range" of control due to the BOSE amp having a very limited and set range of inputs. By connecting up a high power head unit (remembering a 40W head unit is 400% more input power than the BOSE amp was designed for) and the first thing that will probably blow is the input stages of teh amp, followed very quickly by the output stages of the Kenwood as they will see an instant short circuit.
Hopefully, you will be stationary when this happens, as it can fill the car with thick smoke at a very alarming rate making pulling over and evacuating the car dangerous in traffic and at speed.
Listen to what everybody here on the forum says:
Dont mix BOSE and aftermarket stuff together.

Thanks Guys. I'm faced with a decision to revert the HU to stock or change the bose amp? Can I change the bose amp but retain the speakers or do i have to change out all of them?

You either need to stay entire Vauxhall/Opel Bose, or remove every bose component.

I'll change the whole system over time but till i get all the components, the stock Head unit is going back in. Thanks guys. You may have prevented me from incurring tons of expense. Thanks :D

Budget for replacement, as Bose it will kill your headunit
