2018 WRX

[kouroshs123]

I got the rear camera to work. However steering wheel controls stop working after I use the head unit to change volume, track, etc. Basically all steering wheel buttons work until I use the physical headunit buttons to change the volume or track, after that the steering wheel buttons do now work.
Headunit: Pioneer MVH-2400NEX

THANKS!

remove whatever you have plugged into the "WR Input" of the Pioneer radio.
