I have a SWIX interface and have used a remote from an older Pioneer to program it. This has worked fine but I'm missing the voice button, and I think a couple of others.
I have searched the net without any luck and been told by Pioneer that Japan have not released the discrete codes for the AVIC devices.
If anyone out there has the the ability to record the IR codes from their remote (using something like girder and a UIRT for example) and post them that would be much appreciated.
