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.

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
