2018 Subaru Levorg GT 1.6L
Hi guys,

Recently picked up a factory headunit from a 2020 WRX STI VA - comes with the android auto & apple carplay. I've got a MY2018 Levorg 1.6GT with the factory navigation headunit. The new headunit came with an amp also but I did not install this as I did not know amp location for levorg or if it even had one.

It was all pretty straight forward to remove my original headunit and plugged in all the connectors for the new headunit and it turned on! Most features working perfect such as radio, maps, bluetooth etc.

Couple issues - steering wheel controls for volume, speech recognition, source are all mixed up with other functions. Another big issue is volume control on steering wheel and the knob on the unit is not working. I can turn knob down all the way to 0 whilst radio is blaring away. The mute button when pushing volume knob works thanfully.

Guessing i am going to need to figure out the wiring as it is not corresponding with original levorg connectors. Would really appreciate some help here as it is a bit of a shit show. If you have headunit wiring diagrams for both my levorg and WRX unit please let me know :)
