I have a 2009 Mazda 6i Sport. It came with a stock audio system and I purchased everything to install a carPC for an upgrade. Well I thought everything...
I began installing today and got my power ran through the firewall. I got my dash taken apart and began to locate spots for everything. Then I found that I had just one problem. How am I going to get the audio to the speakers?
Here is the deal. The 2009 Mazda has a 3.5 mm TRS (headphone jack - standard) inside the mid console. My initial idea was to run audio from the 3.5 to the 3.5 on the motherboard output and wa-lah audio. I was wrong.
The audio from the 3.5 auxiliary runs through the factory head unit, rendering that jack useless! So what I did purchase was a metra factory wiring harness in case I needed it. I think thats one step closer to what I need but I am missing a component in the designed topology.
Can anyone name that missing component to get the audio from the PC to the factory speakers? Beside an amp.
Im starting the think about keeping the factory head unit in tact some where else in the vehicle.
Thanks in advance.

1999 Mercury Grand Marquis GS with: ASRock E350M1 w/4GB RAM, 80GB Intel SSD, Opus DCX3.120, Visteon HD Radio + HDR-USB, PL-18N wifi, OBDLink Scan Tool, BTA6210 BT, BU-353, Win 7 Ultimate, CF 4.0, Alpine MRP-F240 + MRP-T220, RF Punch 1572s, Kicker 8" Comp.
I disassembled the factory HU and surprisingly the entire face of the unit comes off the main unit. I have not tested yet, but I think I can place the factory HU in the dash and use the 3.5mm TRS inside the mid console. There is gold slotted pins connecting it on two sides, but it looks like it just is input from the front panel of the unit. In theory right now this would preserve my steering wheel controls, FM stereo, and LCD output on the dash. It all presumption right now. I will keep the thread updated.
don't forget about the volume control-- keeping the factory deck cranked up all the way might not work--my ford ranger's radio turns itself down after the car turns back on if i left it too loud when i last turned it off..
Thanks. I should still have control of the volume as well.
Well my attempt failed... sort of. After I disassembled the stereo, I attempted to connect the main unit out of the casing and it did work. The auxiliary was super low in sound. Then I ripped the antenna from the board (oops). I don't recommend the method, its not worth it. I wanted a cheap way to retain my steering wheel controls, FM tuner, and LCD display. Now I have a blank LCD display up there that I might replace with a Pico display. I went ahead and ordered an amp online for the car speakers. It was fun/frustrating trying to use the factory HU.
as long as you had fun doing it!!
