2015 STI w/ Nav and HK Speaker - Steering Wheel Control Issue

Post by Kdgraepsey » Sun Aug 11, 2019 1:31 pm

Hello -
Recently installed a pioneer headunit in my car and its up and running but I am having steering wheel control issue. At initial start up of the car / radio, the steering wheel control volume and seek are working fine however the moment i use the volume and seek button on the headunit the steering wheel controls stopped working or goes disable and maestro module flashing green light.

Vehicle: 2015 Subaru STI Limited with Navigation and HK Speaker Upgraded from Factory

Parts:
Pioneer AVH2550NEX
idatalink Maestro ADS-MRR Module
idatalink HRN-RR-SU2 Harness

I tried reflashing the module multiple times, reset the aftermarket radio & reconnected all wiring just to make sure and the issue still the same. Any idea what causing this problem and how to resolve it?

On other note: idatalink maestro wiring instructions showing i need to connect audio cable from maestro to the aftermarket radio. I already connected the aux cable from the T harness to the aux radio input. do i need to connect the audio cable to radio W/R?

The audio cable should go to aux. It sounds like you have something plugged into the W/R, which should be empty. That is causing the issue.

@Dara DeGrand which audio cable I need to connect to aux? the Audio cable directly from Maestro module or the audio cable from the T harness?

In your application, you can forego installing our audio cable, as it isn't serving any function. Plug the t harness's AUX cable into the radio's AUX, and make sure the W/R is empty.
