Retaining Toyota Computer

[Lyons]

I fitted a Pioneer unit in the Rav4 yesterday and subsequently lost the on board computer that is built within the OEM radio. Upon installation I noticed there were 3 connectors on the back of be HU which are no longer used.

Is there any way if fitting an aftermarket unit of some sort to retain the computer?

What year is the car and what Audio did it have in there?

Del its an 03. Not sure of the model number of the standard system, but its a single cd double din. I'll try and find out.

Not sure what I'm looking for on that site big man?

If you can find me the wiring schematics, I can tell you if it's possible, what to do!

As in just what colour wires are what on the car loom?

Not so much about colours but pin-position and labels!

Hello
I am walking the same path. Was this issue solved? Did you Export signals to different radio?

I have honestly no recollection. I kept the car for about 2 weeks!
