Hmm, that looks really cool, but the BT board costs more than the new deck I bought.

Is it possible to add HD radio to the factory radio using the BT card?

That's not surprising, especially if you bought that radio before @jaysterling's board became available.

Please keep in mind that your radio is 30 years old. It will absolutely need service for its internal power amp and the tape mechanism as both elements have parts that wear out and need replacing.

Unfortunately if you're relying on the tape deck you're on borrowed time as the rubber belts, capstans etc will inevitably fail. There's no practical way to repair the tape mechanism other than to swap it out. The swapped unit will also have old parts in it though.

that's a great question. It would require a new hd radio tuner module, and a way to inject station metadata to the display. If you can live without the metadata display you could take an external hdradio module and use the latest cantaloupe board's aux in.

btw ymmv, but it's not clear to me the added channel content has really been all that compelling. I can take or leave the scrolling text and album art too - if I want album art I'll look at my phone screen.

as to digital broadcast vs analog, what I've usually found in my newer cars is if you can't receive analog due to poor signal quality you probably won't receive the HD-Radio digital signal either.

The cold, hard truth is that HD Radio is a format in search of an audience that never asked for it in the first place.

This is the 4 channel Pioneer that used to be sold by BMW dealers as a "CD ready" radio upgrade. I have seen a 92 convertible with this radio as well. Here's a Jan 1990 Roundel ad showing this exact radio.


EDIT: just noted a later post from Aleman where he clarified that it is a 4 channel radio

A very nice used and tested BMW cassette player. BMW model Pioneer KE-83ZBM. Functions include: cassette, auto reverse, scan, AM/FM/WB. Will fit other E34 and E32 models. This can be used on the E30/E28/E24 with some modifications to your wiring. This is a 4-channel output radio, while the E30/E28/E24 used a 2-channel for the most part. This unit is designed to be used with a factory amp. A rare find.
Here's the back of the KE83BM - note 4 speaker connectors, and a CD changer connector (the round "DIN" connector).


As @Aleman / OP mentioned earlier cars had the external fader in the HVAC panel, and 2 channel head units like the Alpine CM5905 and CM5907.

Take a look at this Jan 87 E30 brochure - note the CM5907 and the fader knob in the HVAC panel (man everything about that pic is just perfect isn't it...).


Some 87 cars and 88 IXes still had these fader buttons too - so they were NOT "CD ready". Instead of the 5905/7 they came with a 2 channel version of the Pioneer radio, Model KE-81ZBM. In fact my 88ix lachs/cardinal coupe has this exact setup. Check out the KE81 in this Motorweek video clip


KE81 front face - no mode switch on right end

KE81 rear face - no CD connector, only 2 speaker connectors

KE81 closeup on the connectors


Finally, since the rear of the 5908 slider isn't pictured on this thread I've included it here. Note again the CD connector and 4 channel speaker connections.


Based on all this info, it's safe to say that if your car came with that external fader knob, it had 2 channel wiring and is not "CD Ready".

It looks like radio #5 is a Blaupunkt C22 (BP4836).

There is also similar model C52 (BP6262) and a host of 'Bavaria' models.

C52 (BP6262)




Bavaria C III BP1830



Bavaria Electronic CD



BAVARIA C BE0728



Bavaria C Business BE0774



Bavaria C Business RDS Pioneer KE-92ZBM



BAVARIA C Professional RDS BE1801



BAVARIA C Exclusiv BE0729



Professional RDS BE2455



Bavaria C Professional BE0776



Bavaria Electronic CD II SCD09 What's interesting about this one is that BMW lists the CD43 as the superseded model in the E30 ETK ( 65126909885).

I have two of these. One works/worked when stored, and the other is a parts deck.They are cartridge CD decks. Disc goes in cartridge, cartridge goes in the deck.
I have a box of NOS cartridges for them as well

That's awesome. I remember an old Mac computer at school when I was a kid had a cartridge CD-ROM drive and I played the game Cosmic Osmo on it.
