Before I start, I have searched through countless forums and tech sites for a definitive answer to this question and haven't been able to find it so here I go.
I'm interested in buying a aftermarket double din head unit (touch screen/Bluetooth/DVD) but I want to retain ALL buttons on the Steering Wheel Controls (including the bluetooth cell phone buttons pick-up/hang-up).
I am fully aware that I would need the ASWC-1 module. (http://ae64.com/ASWC-steering-wheel-interface.htm)
But, I have read that most people lose the correct Bluetooth buttons function which is something I am not willing to sacrifice.
And I will most likely be ordering SVXdc's wiring harness since everyone who does this seems to recommend his. (Subaru WRX radio harness pin-out)
According to ae64.com:
With that said, I have no idea which head units are supported and have no idea how to sort them out.Will the ASWC-1 retain all of my SWC buttons?
The ASWC-1 will "see" all of your steering wheel buttons (6 on older Subarus, 8 on newer models with the extra phone/Bluetooth buttons). As far as the module is concerned, they're all just buttons. It doesn't care what the label says on each button. You program the module to determine what remote control command a button sends to the HU. Each button can do any command that the HU supports. That last part is key: Many HUs don't have remote control commands that correspond to all of your wheel's phone buttons (even HUs that have built-in BT). It's a limitation of the HU itself.
Has anyone done this and was able to get the Bluetooth buttons to work correctly? If so, what head unit are you using? And what do I need to do when I install?
For my 2014 WRX Limited Hatch with stock Head unit (not the navi).
