Corolla E12 prefacelift Steering wheel control problem with aftermarket android radio

Hello! I bought a android radio from Aliexpress and it came with same steering wheel connector as in picture. My car is 2004 Corolla so it have same connector as in picture upper one. Does anyone solve this problem to get SWC work in prefacelift Corolla?

Hi,

Not an update I have done, but seems you need something like one of these Connect2 adapters, best to contact them to ensure its compatible with your new unit,

Other connectors are just like in original radio. Only that one is different. Is it possible connect wire by wire? Radio is working nicely, except steering wheel controls.

Hi,

They make cheap cable / plug adapters for the other speaker connectors etc, so if the steering wheel could be done that way, surely they would be around.

Its not just wire to wire plug compatability, its the electronic and logic  compatability as well.

As said, you also need to check that the Connect2 unit is compatible with your model Corolla and Android Head unit.

Hi,

Thanks for answer.

I sent them a question about can they help me with adapter. 

Here a pic from new radios back (low left is the connector where steering wheel contorls wire goes). I've never seen that kind a connector in any aftermarket radio.

Hi,

It looks a good physical match for the old radio, but they seem to come with a hefty price tag.

Can only see Android 8 or 9 units on AE.

What you have to remember is your Toyota unit is over 15 years old and Toyota tended to use their own wiring /connection standard in those days.

Modern aftermarket head units are much more compatible with each other, though not sure about these Android units connections ?

Hello,

Like I said, other connections is just right.

Seller advertises that the radio is compatible with SWC, so I'm just trying to figure out is it anyhow possible fit facelift connector to prefacelift connector.

If you check the adapter here, the cable is similar and you can see C1 and C2 plugs listed as SWC controls. It looks like it goes wire to wire, so if you can isolate the wires, you can make your own adapter, but they do come cheap enough for you not to bother.

I'm putting this link only because i cant isolate big enough pictures to link here directly, and i dont have time to find a way around that now.

So do not take this as any advertisements i'm posting it just because they have all wires marked

Thanks everyone for answering!

Any tips are more than welcome (advertisement or not). It looks like a good size, but am I only one who think, that those pins doesn't match with each other? Look's like one pin goes to empty hole etc. Connects2 said that they can't help in this problem. It looks pretty impossible right now..

Hi,

If you see this link it describes the two versions of SWC used on the 2002-06 uk models.

With it being so old the pictures links are no longer up there, but you should be able to work out something from the text.

Seems the Resistive ones are quiet simple as the diagram shows, said to be from a Corolla but unable to verify....

With the info on that link you also need to know what signal / paths your Android is expecting to receive, so hopefully its manual or helpline can advise ?

With that info you may be able to connect the two, or find you need some additional  interface unit /electronics...?

Could be an expensive mistake if you just plug and try !!

Hi,

Thanks for info. I need to study this more when i remove radio to fit it bit more better. There was a label of wiring diagram on the radio, so i have to see what it says.

If anyone know bolt on adapter or something, still tips are more than welcome. Internet is "full" of adapters with ISO-connectors, so maybe its possible to get one of those and cut the wires and solder them in android radio connector.

Hi,

Think you need to mention which type of SWC you have, the small buttons built into the central boss of the steering wheel or the type with a lever arm/ paddles  just under the wheel as they function in very different ways as that link shows.

Hi,

I have those paddles type controls under the wheel.

If I decide to try cut and solder those wires, something like this (upper one) maybe should do the trick?

Does anyone know can something go wrong, or is it even possible that could work?
