I have removed the origional head unit and found that the wiring connections are unique and not labled.
I'm happy to sacrifice the additional cameras and steering wheel controls. I just want uk sat nav and DAB radio. This is the origional Panasonic head unit.
Are there any experts out there who can advise me what the pin out connections are. I think I just need to connect in an ISO connector whilst keeping everything backwards compatable, unless adaptor cables are available. The additional antennas and even a replacement reversing camera can be connected directly to the new Pioneer head unit.
So far I have not been able to find and reference to this particular head unit anywhere online.
Also, I assume Alphards are not fitted with OBD sockets as I've not been able to find one anywhere.
Any help or advice would be greatly appreciated.
