Aftermarket car stereo

[Kardell]

I have never suspected that replacing this 2 DIN 6CD car radio + subwoofer is going to be so painful.
I have bought Autoleads PC9-404 and Autoleads PC5-90 but this does not work of course.
I can see that the only way to make it work is to DIY or spend $100 on some super dooper adapter that can probably do other stuff like control the flight of a ballistic missile.

Can you see any alternatives or do I have to return all the items?
By the way this PC9-404 does not make sense it is just an extension, no crossover or anything. Who would need this?

Best regards,

I'd suggest returning everything and purchasing through Cruthcfield.com. Nice products, and great customer service. They'll make sure you have all components, plus they will guide you if you get stuck during the installation.

Hi.
At first would be nice to know is there BOSE or Non BOSE system? Then which is new stereo? After that would be much easier to help you. PC9-404 is a Non BOSE (half amplified) connector and if car is BOSE then you have already a problem. To check bose-non bose, remove stereo and if no wires go to 8-pin brown connector then it's bose (need another adapter PC9-410). If wires are connected to pins 3,4,5,6 then non-bose (this PC9-404 is correct one).More exact info at first get things going much faster.

Hi again,
Thank you for you input.
So there is no markings on the unit itself only something about Dolby Digital. There are cables going to the brown connector, actually wires going to all 3 plugs. The problem with PC9-404 I see there is more cables going into the corresponding connector, PC9-404 have only 2 cables going out and I suspect my subwoofer or something else will not produce sound.
The replacement is SONY WX-GT90BT BT with supplied connector like on the picture. This connector corresponds with the car's connectors but the wiring does not and we are missing an adapter for the 3rd connector and I think PC9-404 is not sufficient.


Not sure what is the point of this black connector on the below picture, but this is what was supplied, it looks like an extension to the existing connector, wiring is exactly the same on both ends.


Best regards,

[ReinS]

Some good news and some not so good. Connect 404 between sony and car connectors. Just in case check that red and black wire matching car connector wires. Those white and grey wires are for front speakers. From red connector RCA plugs to sony rear audio out. Blue wire from red plug need to be connected with sony blue/white striped wire (amp power). Red connector connect to car 20-pin black connector. Now bad news: Looked wiring diagram and find out that your sony don't have blue ant remote wire, so you have to find switched +12v to feed PC5-90. Otherwise radio reception would be poor. If stereo not remember preset stations when you turn it on next time, then you need to connect red (ACC) and yellow (Battery + for station memory) wire together. If this causes battery drain then you have to find switchable +12v for red wire. I took mine from ignition switch S pin.

Hi again ReinS
Thank you for your input.
That is fine, I can sort out radio later on. I am not listening to it really much.

The red and black do not correspond to the right color from the car's wiring, but some red/blue and brown one.
Moreover another two wires are on different position.

If you could help me to at least light this new radio up, so I can check if it works.

I have attached some pictures of the connectors:

1st pic is the power block
2nd is audio I think. Can't really see

Did you have a cd Changer? As that explain the 3rd block?

Red/blue is main power
Thick Brown is earth
Green is switch live
Brown with stripe is lighting

You can see which pin does what on that last picture

Just look at what you have. You don't even need the audio connectors that you've bought.

That sticker on the back of the old audio radio tells you exact what pin/wire does what. The Sony will be super easy to wire up.

I don't have a CD changer in the glove box, this unit has 6 CD changer inside the unit itself, so not sure why there is this 3rd socket on the right on that diagram, there is no such socket on the stock radio itself, just the 3 horizontal ones you see.

[ReinS]

Multi-pin connector III, 8-pin, black
2 - Anti-theft signal
3 - Data Link Connector (DLC)
7 - Supply voltage B+ (--> Sony red and yellow together).
8 - Ground (GND) (--> Sony black).
You only need pins 7 and 8. There is no switch live wire as iconic78 assume. Switched live comes from can-bus. Brown connector is for front audio. Rear audio is taken through that red connector with RCA. Connect red to car 20-pin black connector and blue wire from red connector with sony blue/white striped wire (gives switched + to rear amp) and RCA-s to sony rear audio out. Those 2 orange striped wires in 20-pin connector is for can-bus and not needed for now.

I have no idea how to remove pins from this Sony female connector.

[Kardell]

I have connected all, I mean checked that yellow is joined with red and goes to red on Sony, then this brown from car which I assume is ground next to red is connected to black on Sony.
On ignition he device is not coming up even when pressing OFF button which is ON/OFF according to documentation.

Possibly this device is dead, the fuse is ok.

[Kardell]

On the car black connector I have
(pin 8) BROWN - 12V
(pin 7) BLUE-RED - ground
(pin 3) GREEN-BLUE - 12V
(pin 2) BROWN-WHITE - 2V

I have used this junction circled on the picture to lead 12V from yellow to yellow and to red. I have 12V on an bigger pin where yellow goes in but not on the nearby red. It is a short red wire that was there all the time, I was not fiddling with it, but there is no voltage on it.

[ReinS]

I have no idea how to remove pins from this Sony female connector.

First one what i found: https://www.youtube.com/watch?v=ddZpGBTsnlI

On the car black connector I have
(pin 8) BROWN - 12V
(pin 7) BLUE-RED - ground

Are you sure? Should be vice versa as in my earlier post. It's taken from Bentley. Took my stereo off to be sure and for sure blue-red is 12v and brown is ground.
Take red wire apart and connect to that yellow junction. Now remove red and yellow wires and reassign vice versa in sony female connector. Now when you plug connectors yellow should be connected with blue-red wire from car connector and you should be good to go.

[Kardell]

Actually when I pushed voltmeter probe harder inside the red one at the radio end it also shows 12V, so I have 12V on yellow and red and grounding, still radio not coming up with ignition is on. Checked the fuse and it is ok.
I think I have a defective radio or I have missed something. I have not connected RCA yet, but I don't think this would stop it from working.

[Kardell]

Hi ReinS
I have then swapped as you said, so I take voltage from blue-red all the way then split to yellow and red at the very end radio socket, but in result blown the fuse.
Brown goes to black all the way to black.

What about this pin 3 one that also has 12Volts?

[ReinS]

Pin 3 is diagnostic wire and is used with audi original stereo only. Maybe there's really something wrong with this stereo? I had also sony few years ago in my car and connections were made exactly as i said. Worked like a charm. Now i use alpine and only difference between sony and alpine connections is that i connected red (ACC) wire with ignition switch S pin. Behaves more like original stereo. Alpine yellow is connected to car blue-red and black to car brown. All works as should. Actually there's no difference is it sony or alpine. It's a wiring standard.

[Kardell]

[car]_________________________[Sony]
red-blue ------------ yellow --------- yellow
___________________\------------ red

brown ----------------black------------ black

and the fuse went off
these are the only connections I have looked at should I remove any other pins from that black connector just in case?

[ReinS]

Those two connections are correct. Something is causing short circuit. Is there wires in Sony female plug which is connected with green-blue or brown-white wires in car black plug. If yes, then remove connecting wires from Sony female plug. Leave only those two red-blue and brown connections as is.

[Kardell]

ok, only this brown-white was reaching the other end, disconnected, I have to get a replacement fuse to proceed

[Kardell]

That's me again!
replaced both fuses, checked voltage, radio does not come up. I think I am sending it back.

ReinS - great thank you for your help and patience.

[ReinS]

No worries. Also you can check it with battery charger if you have one or just with some 12v battery. Connect red to + and black to - and radio should come up. Yellow permanent + is needed for settings and preset stations memory.
