Harlan Posted April 17, 2023 Share Posted April 17, 2023 2018 RAV4. I replaced the radio head unit with an aftermarket radio. Now my right side steering wheel controls aren’t functioning. Is there any wiring from the right side buttons that would be affected by changing out the head unit? I understand the loss of the left side controls, but not the right side. Any ideas? Thanks.

Toyota Owners Club Posted April 19, 2023 Share Posted April 19, 2023 Are the left hand controls for audio as well? I'm sure there are patch leads to get the steering wheel controls to work with aftermarket audio systems. May have to run through an interface but if the wheel controls aren't that crucial to the function of the systems then maybe avoid an expensive workaround Quote Link to comment Share on other sites More sharing options...
