2014 Legacy HK BT No Nav Steering Wheel Issues

Hello,

I have the Maestro RR with the SU2 wiring harness hooked up to an Alpine ILX-107 in my 2014 Subaru Legacy. I flashed the RR unit for my car/configuration and the steering wheel controls did not work. Volume up would mute it, volume down would mute, and seek/all other buttons did nothing. Reading through the forums I noticed that people had been instructed to run the 2011 year software, which I then did, and it kind of fixed my issue? The Volume Up/Down, Seek Up/Down, and Mode buttons all function correctly however the Siri, Pick up, and Hang up buttons do not work at all. With the dash apart I clicked on all the steering wheel buttons and noticed that the three buttons that did not work did not make the Maestro RR light up at all. The three working buttons caused a green light to flash.

Additionally when running the 2011 software I ran into OBD2 issues and none of the gauges would display correctly. If I re-flashed to the 2014 tune the OBD2 worked fine but the steering wheel controls stopped working again..

I am wondering where to go from here?

Thanks in advance for the help.

Hi, just to piggy back; I am having a similar problem with a 2014 Outback HK BT No Nav and an Alpine ILX-207.

Thanks

Sorry for the delay I was not receiving notifications.. I tried as 2014 Outback HK BT no Nav and experienced the same issues as I had with the 2014 Legacy Rom - buttons were not responsive (though it did fix my OBD2 port issue) Do you have any other solutions?

For all you who have replied to this thread and do not have the backup camera working - you need to follow the instructions found at the bottom of this thread: viewtopic.php?t=18525

I followed the above instructions and it worked perfectly. Even the Crutchfield rep I had did not know this fix existed, but that should solve your issue with OEM backup cam.

Flash as the 2012 with harmon with BT, non- navigation if the 14 doesn't work. The wheel itself can have several different resistance pads in it, which is where the issue arises.

Great - I will try the 2012 tomorrow when I get the chance to pull it out of the car. I will update with results once I get it flashed, thank you

Thanks All! The wiring instructions for the back up camera were spot on. I'll reflash when I next get a chance to take the unit out.
