My first post so please be gentle...

My lovely new cooper arrives at the end of this month, however due to brochure and dealer confusion I was under the mistaken impression that the CD changer came with the radio BOOST. Now that it's too late to change it I have discovered it doesn't.
To get the dealer to fit this would cost around £450, which I really don't want to do, so my question is; can anyone suggest an aftermarket solution which would provide similar results (as far as I understand it's basically an uprated amp and extra wiring)? I don't want to rip out the factory supplied head unit unless I absolutely have to.

Many thanks

Are you after a CD changer to go with your headunit then? I'm sure someone suggested a model of CD changer that might be compatable. Would the BMW ones work, my dealer has a special offer on them at the mo!

Also, you can buy little boxes of tricks that convert the signal from a CD changer (can't remember the make, sony perhaps?) and turn it into a radio feed. All you have to do then is tune into the radio...

Don't despair, there's a few options about. Also, try doing a search through the forum, this has been covered a few times before I think so should prove useful.

Sorry I wasn't very clear in my first post, I will have a factory fitted 6 disc CD changer and the tape head-unit that comes with it but no BOOST. I was looking for a way of getting BOOST performance without replacing the head-unit or other really major (expensive) modifications.

Apparently the 10W to 20W power increase gained from the specifying BOOST is gained not by speaker upgrades but by an amp in BOOST head-unit, so hopefully an external amp would provide a similar effect?

As you've probably guessed I'm not particularly clued up on ICE stuff.

Ah righty...

There's a few options then:
  • Find someone who has replaced their BOOST radio with something else and hasn't sold it
  • Buy a small external amp to power the speakers
  • Buy an amp and new speakers
  • Upgrade the headunit
I'd say that the best option is to bite the bullet and upgrade the headunit, but you run the risk of the CD changer not working. Therefore, if you can't find anyone who wants to sell their BOOST unit, buying a small, cheap external amp should provide a similar upgrade.

Some people say that the speakers used with the BOOST pack are different to those used on basic radio cassette models, but I don't know. I'm sure someone will be able to make this clear soon...

Hope that helps!

Ah I see, thank you that's most helpful.

There's one point I think I can clear up for you; according to the audio guy at my dealers the speakers for both the BOOST and non-BOOST versions of the radio are the same ones (although as everyone probably now knows dealers can often get it wrong).

I think my best option is to go for a small external amp, any suggestions as to what I need to be looking for?

I'm pretty sure that the BMW cassette deck doesn't have pre-outs, so you'll need either an amp/amps that has/have high-level inputs or a converter that is available to change the high level (amplified output) to pre-out (unamplified) to be re-amplified by the new amp/amps. That said, a new head unit is probably the better/cheaper/easier option. I think the CD changer is a Sony unit, so perhaps a Sony head unit would be OK? I'm sure a decent audio centre would try this out for you before you commited to buying it.

Excellent, I think my first port of call would be to find someone selling a BOOST ‘CD changer’ head-unit, if not bite the bullet and visit my local car audio shop and talk to them.

However I think I’ll wait until I've taken delivery of the car before I decide, who knows the standard setup may well be just fine (although I doubt it'll cope well with my CD collection).

Thanks for all the suggestions, much appreciated.

Have you checked that you cannot change the spec on your car?

I understand they can change the spec right up until your car is allocated a chassis number.

I also would have thought it would be a reasonably easy task to ask for minor spec changes late in the ordering process but my dealer thinks otherwise...

I'm not too worried though, I dare say that any decent audio specialist should be able to help; and for considerably less money than BMW.

Cheers for the link, however my car's been ordered with the BMW CD changer installed and I'd hate to have to change it as I'm sure the unit's pretty decent.

The easiest option would seem to be getting a new head-unit that can drive the BMW changer (made by sony I believe).

I made exactly the same mistake with my car - got the autochanger and just assumed it came with the BOOST. Don't be too disheartened, I've found the standard setup works well enough with the autochanger and although the sound could be better, its still acceptable.

I too have the standard head unit and the CD Changer. Sounds good enough to me.:)

The CD Changer is a dealer fit so I don't understand how they can not change your spec.

If you can't change then just wait until you get it and live with it for a couple of weeks. You probably won't want/need to upgrade.

Cheers:)

My dealer is telling me that an aftermarket head unit CANT be installed........is this true? Says the Wave and Boost are a unique size, it doesnt look that way to me though!

Basic aftermarket units have outputs of 25 to 45 watts, can the standard speakers handle this, or would they need upgrading too?

Id be grateful if anyone has any knowledge on this........

Size doesn't matter, it's what you do with it that counts. You can buy a simple adapter plate made by autoleads so you can slot in any standard sized aftermarket headunit.

I think your dealer is correct, but a little 'too' correct. You'll find lots of people have changed their headunits, me included.

Hope that helps,

Dom
