aurion head unit upgrade need help

[kcir]

Hi, i tried the latest toyota touch screen head unit PZQ6000521 on my 2008 aurion. I got an antenna patch wire, the audio and bluetooth work no problem. But the steering wheel controls including DISP button are not working. did I use the wrong cable? or do i need another patch cable? could anyone who has done this before advise the part number? Thanks

Hi Sportivo2007,it is the left one i am useing at the moment. Do i need the other one, what is the part number please?

[sportivo2007]

Your using the right harness the one on the right is the speed sensor , i dont think that will make anything different , check if you can adjust the controls thro the settings .

The one on the right with purple wire is PZQ60-10040?
