2009 Genesis 4.6 V8 Lexicon system........

[MADDMOE]

....so my radio (2nd one since I bought the car 15 years ago) went dead.......so I'm looking for a schematic of the wiring coming off the back of the headunit to see if I can wire up this....

Along with this.....

...to see if I can just play my sounds through my cell and then I can keep my headunit to control everything else, because everything works on it just NO sound ....

...any help will do on the correct electrical schematic , thanks in advance

The Body Electrical manual is 977 pages long. It starts with some general head unit wiring pin outs on BE-1. BE-35 goes more into it and BE-132 has the amplifier pin out.
This system uses a digital signal and an analog signal from the head unit to the amplifier. There are apparently 4 low level (FR, RR, FL, RL) channel 3.2v outputs from the head unit that you could pass into your digital signal processor and then your own amplifier. Or you could I suppose try rewiring it so your digital signal processor injects analog signals here to be amplified by the car's amplifier.

There is of course 17 channels total and the rest are handled at the amplifier in the trunk. It of course is doing some digital signal processing and it is amplifying. Some signals are going to be purely analog like AUX in of course. I don't know how many other signals are just digital. BE-135 says the amplifier is amplifying 11 channels. On the pinout, I count 13. It has two subwoofer circuits though and the amp wiring shows two circuits to one subwoofer. So its a dual voice coil subwoofer. Usually you'd just wire them in series or parallel. I have no idea why you'd have two discrete circuits but I guess at least one more speaker is dual voice coil or something to get 11 speaker amplification out of 13 circuits. They say its a 17 speaker system though so IDK.

I tried tracing the wiring harnesses but there are so many in this car that it looks like the veins or nerves on the human body. I couldn't find a simplified view of amp wiring or speaker wiring only.

So overall, I can definitely tell you the head unit has an amplifier and a fan in it. It says its driving front and rear channels for left and right respectively. The speaker layout doesn't show something like just a "front left" speaker. It shows "front door 1, front door 2, front door right tweater" etc things like that. The amplifier is also doing a lot of digital signal processing. The AM/FM antennas go directly to it for example. The amplifier in the trunk may actually not even be amplifying some signals and just passing them digitally to the head unit for its 4 speakers. The whole system is controlled by a MMCanbus (multimedia canbus) that controls HVAC and audio as well as a few other things. Its saying it uses a MOST bus which is a Media Oriented Systems Transport bus. Believe it or not, it uses optical fiber cable for data transmission. There's 2 or 3 of these connectors on the amplifier so I do believe the amplifier and head unit are working together seamlessly. This is probably the MOST25 standard which can handle up to 15 channels. This is why I'm assuming they needed basically two amplifiers because there are apparently 17 channels.

So to sum it up, get a nice bluetooth speaker. There is little chance you're going to get this to work like you want without a lot of work. You can probably repair or replace your existing stereo, inject signals in at the AUX connector or FM antenna but anything beyond that is going to be very complicated without completely replacing everything with new. There are the 4 channels at the head unit but I'm not sure that would be the sound quality you're looking for.

....thanks and your right a nice bluetooth speaker will solve this problem lol
