Cd53 wiring

I know this has probably been beat to death but after hours of seaeching i cannot find the pinout for my cd53 radio connector, installed aftermarket head unit with proper adaptor but there is no sound. I have the flat 16 pin connector.

Pin 1-none
Pin 2-blue/red
Pin 3-yellow/red
Pin 4-none
Pin 5-none
Pin 6-brown
Pin 7-brown/brown
Pin 8-none
Pin 9-white with yellow spots
Pin 10-white/brown
Pin 11-none
Pin 12-brown
Pin 13-white
Pin 14-white/red
Pin 15-red/green
Pin 16-purple/white

All the pinouts ive seen for this style connector have pins 1-8 filled with speaker wires so im a little confused as to why mine is different. Everything else works on the unit probably because the power and ground wires are still in their normal spots and so is the can bus wire.

Yes, the HU must be designed to be compatible with DSP.

The original HU feeds the amp in the trunk, and the amp drives the speakers.

you have dsp, your aftermarket head unit will not work...

your best bet is installing a sub, a AUX port

and if you must you can upgrade speakers

Im quite satisfied with my aux port and my mixcloud

10" in the trunk

but anything shy of a complete strip and rebuild

Its definitive definitive true,

so the DSP head unit is encoded and yada yada yada, its needed to run the amp in the trunk,

the speakers are special the amp is special the whole system is needed to work together or none of it works...

you cant just jump it out.. its all encoded and compressed and decoded.. Its like its own computer system...

what people do is strip it and install there WHole own system.. but even that you still need to hold on to parts of it to make the interior of the car work.. *guys put components in there glove

honestly its not worth it... WHAT is it you want to do? I have added a AUX and a sub woofer to my DSP system (*i have a cable i plug it in to my phone when i drive i have the whole internet for audio)

Well, my mid has dead pixels to the point i cant read any words at all on it and my buddy with an x5 gave me his xtrons touch screen head unit and for the most part the x5 and the e39 got the same sound system but he must not of had the dsp where as i do unfortunately

yeah guys some times put the mid in the glove box (*because you need that for everything to work.. its connected to the cluster and the central locking system) then install a 2nd system over the exsisting one..

new amp, new speakers, new head unit new wire

you can send your mid out for pixel repair?

my mid is in good shape, I upgraded my tape deck to cd54, installed a AUX and added a sub in the trunk,

sorry... you dont have many options here, and none of them will be cheap to complete (*except for the route i went)

IDK where Dennis is, He is our e39 audio specialist He knows this system in and out,

other options are to buy DSP compatible head units (*they are not cheap)

Ya i tried the mid in the glove box trick but it didnt work.. I dont think the mid was working, there was some word on the screen but i couldnt read it because of the pixels being dead lol. But ya i think im jus going to jus repair the mid myself, doesnt seem too complicated and the led strip is readily available.

The DSP amp needs a signal from the radio to power up. The radio is the cd or cassette deck in the dash. I have DSP and did quite a big search on the subject.

In the time I have been gone did everyone forget about the reisler ibus interface for Android head units? Works great and allows you to use the DSP amp with an aftermarket unit

I no longer have an e39 but back when I did people had been using it with great success. Here's the site: http://www.reslers.de/IBUS/index.html

This product is known to operate with the E39 DSP system. It is also supported in the USA:

Hi,

Burning 2nd - thanks for the mention, much appreciated ! However, my focus isn't on the various OEM audio setups and mix and matching those with other OEM BMW modules etc. It always has been and always will be high quality and reliable aftermarket audio equipment for me !

Grizzygary - Do have a search on this and all the other BMW forums as the pinout diagrams for each of the oem audio setups have been posted many times in many similar threads. I know you've done this, however also look specifically for threads where the head unit you are trying to install is also mentioned for more focused results and potential things to try in order to resolve. As you have DSP, then yes, things are more complicated and there's only 2 head units which can directly support the E39's that had DSP and where the owner wants to continue using the OEM DSP amp and speakers. Those are the Dynavin N7 and the Avin Avant 4. The N6 is the older version and I think the Avant 3 might have also had DSP amp support, I'm not sure. If you have one of these head unit, refer back to their support for more guidance. If not, then if you have another chinese replacement unit, search out threads to see which ones, via the Resler Interface/Ibus App can then work with the OEM DSP amp/speakers (Xtrons is one brand that has units) . IF you have a premium high quality brand head unit, then these won't connect to the OEM DSP amp/speakers ( I think there's an old workaround type way of doing so, but it's convoluted)

Cheers, Dennis!
