My New 2013 Mazda5 GT - Stereo Upgrade Time

[ckappycycle]

Pickup, hang up, talk steering wheel buttons are controlled by 1F pin on 0920-601A connector (big one on the bluetooth module).

If you're using generic android stereo with SW1 and SW2, you should connect 1F of 0920-601A to SW2 on android stereo via 330 ohm resistor. And SW1 goes to 1N of 0920-401A (main radio connector).

If some canbox controller is used (generic chinese, for example), 1F pin on 0920-601A --> pin5 of canbox, 1N of 0920-401A --> pin15 of canbox.

I've attached the schematics which I used for reference when I was connecting android stereo with canbox (although, all buttons are connected via SW1/SW2 in my case, not canbox).

Absolutely everything works as intended, including overlay displaying which door is currently open.

Also, you can definitely repurpose existing BT module by ripping out the connector and reusing it for a cleaner installation. I screwed it to a piece of plastic and soldered everything neatly. This BT connector is a perfect place to connect sleepy Pi / any sort of additional computer one want to use. This connector has ACC+, BAT, GND, CAN-H, CAN-L, I wish I had time for this.

Thanks.
I'm still sort of wondering if you needed the CANBus adapter like the PAC. The Crux I think is just for the SWC which the headunit may take care of.
Assuming generic canbox is equivalent/copy of PACs little interface device?
I would assume the info button and the A/C controls drive the right and left side of the display without going through the radio.

Off hand do you know if the VSS (speed) I thought was on the 24 pin but maybe that was on older models?

The PAC for $140 might make 20-30 minutes of life easier and eliminate the question of what happens without it but it does require power and probably needs the old BT module plugged in to get the second steering wheel circuit data into the CANbus.

The PAC unit was so plug and play, no need to even think about anything else. Just get it
