Guys

I'm in the process of acquiring the original cassette player for my dash, but heard somewhere that you can buy separate bluetooth audio units that go behind the dash, that have preouts etc.

Thus keeping the original look to your dashboard, but still having the opportunity to stream music from your iphone and run off amps, subs, etc.

Anyone tried these, or even heard of them for that matter?

ive not seen anything that can do that with old stereos, but would be awsome although i should imagine tricky to do and the stereo would also need the function to be able to play it, only thing ive seen is a bluetooth cassete adapter (google it)

or these, but the stereo needs to have aux in ,looks quite handy and no messy cables and can just unplug it from the stereo face and kept in the ash tray

what your saying would be the same sort of thing- but stereo opened up and a wire connected in to the back of the aux imput or whatever, rather than in the front, and wired with power

If you plug anything into the actual old head unit, the sound is going be very poor at best, with the lack of power in those old units.

What I was looking at, was a completely separate unit, that is fitted behind the dash entirely, and it has it's own pre-outs etc. but only has bluetooth capabilities, meaning it's only used for iphone/android music streaming. Therefore although the old stereo is in the dash, I would probably not have any connection/power running to it. It would only be there for aesthetic reasons.

I've seen one, im sure of it, just can't remember where :?

BUT- the stereo still needs some sort of capibility/function for it to play

ie - you need to be able to tell the actual stereo/press a button, for it to know the source you want to play, like the way you press the button to select tape or radio - ie an "aux" input, and the bluetooth unit will still need to be wired in to the stereo via a socket or circuit board or whatever

Not necessarily I've been using a sony bluetooth head unit, and all controls are done on my iphone. Soon as I get in the car, it pairs with my phone, and then from me pressing play on my phone, sound appears.

So imagine that head unit, but with no other functionality other than what I just described.. bingo.

i also have a bluetooth head unit in my car that does the same, but remember that unit is made for it, but when you press cd, or radio..it changes over and you can re select - so surely you need a ay to "select" the bluetooth , so if you play a cassette or listen to the radio, you can re select it , or switch between

or maybe just un pair the phone, then re pair it ?

looking on the site, they charge £105 for what looks like a proper full recondition and service, and also add aux imput in the back

Yeah they look pretty damn good! I think it will add up in the end, restoration, blue tooth etc. plus I'd still be skeptical about the quality of the sound coming out of those old units, unless he's completely rebuilding what's underneath the casing!

I've just gone and brought a pretty good looking Alpine CM5908. Should of got a rubbish one for £20 and sent it on to these guys to restore!

One thing I would say, is the originals dont have phono outputs so wouldnt be able to get any amps or anything like that going, which means the quality of sound issue is still present. Alot of money to put into something thats not gonna sound too good.

some do, like some of the blaupunkts for instance, aswell as aux in

there isnt really an e30 original, there are many as it was all optional extras and with e30 production spanning such a long time stereos moved on a lot, so you really need one from the right year to match your car , what was orignal/period dealer fit for a very early 80s chromie, would be very different to a 1991 facelift car for example,and many in betweens , your talking a decade of car stereos

situation rescued , he said had problems with people sending them without codes, and some parts hasstle, so it wasnt worth doing

BUT :D , after me assuring him mine had code and was actually working ok. hes came around to doing it

he said- unit fully serviced and cleaned,new stem bulbs, tape deck serviced, new aux imput comming out the back , £50 plus return post cost :D :cool:

cant argue with that , he also said he can change the bulbs (screen color) of units to match the car , i dont need that doing as mine is amber already but thought id mention it

so im going to get mine off to him

Sounds like a plan right there!

I think I'm going down the route of installing the old BMW stereo in the dash, but no connections to it, other than perhaps a power lead, so the time is displayed.

Then put a modern unit in the glovebox, with preouts to a sub etc in the boot. Might hide or cover the unit, so it's not obvious. Only need the bluetooth function tbh, so no need to toggle buttons etc, once it's set up.

Just to clarify, I'm not an 18 yr old who wants ridiculous bass and awful music, just want a good car filling deep sound, whilst not compromising the look of the interior. From looking at everything I think this is the best option.
