Hi I've been looking at getting a replacement circuit board (PCB) for the steering wheel stalk, so that it would be possible to use aftermarket head units for the pre-facelift Corolla. I've currently been using a Pioneer HU for about a year now, and been missing using my steering wheel remote... My plan is to design a new PCB that can be assembled to be able to use several head units. It will be a DIY kit, where the plug for the remote must be salvaged from the old PCB, so some tweaking must be done, but my plan is to keep it to the minimum. Would anyone be interested in modifying the remote? I'll be designing the PCB, and the more people interested, the cheaper the PCBs would be. Let me know which head unit you have, and I'll see if I can get the design to suit it. I'm not doing this for my personal gain, and I'll try to keep the price around £20, but that depends on the number interested. By the way, does anyone know any really cheap PCB manufacturers? :)
