The steering wheel controls, bought for my Toyota Avensis T25 (built in 2003) is only recommended. I have replaced the work of my radio Avensis against a JVC 2-DIN radio. To the steering wheel remote control (soft and loud, in front, back, fashion and mute) to use, I bought this adapter. It works flawlessly and is installed without much knowledge. The adapter replaces a required ISO adapter and makes everything a little easier.
In summary, I was pleasantly surprised that all the functions of the steering wheel were supported and the installation was super easy. Thanks for keep it up!
