I also upgraded the dual climate air con control. As Full-Throttle said the Air con control board must be replaced to part # is: 89660-xxxx otherwise I would not work. To my surprise that both boards(manual and digital) are exactly the same, possibly the firmware are different so that the manual board does not work with the digital controller.
The dual climate control looks a lot nicer than the old school manual one however the manual knob is a lot easier to use in my opinion.
Also as Full-throttle has already mentioned, the dual climate control on my ATX only produces cold air, not blowing heat air at all, which is the compromise that you need to take if you decide to change over.
I paid $30 for the controlling board and $30 for the digital dual climate controller from a wrecked presara, great value for the upgrade.
Also, DO NOT try to get the Camry dual climate control to use in an Aurion, although they look the same. It would not work and verified by me.
I also took the chance to upgrade the wood grain middle dash, the TRD gear knob, the TRD Seats, automated rear mirror and trims. My ATX looks a lot nicer now.
