Help identifying serial communication with a logic analyzer

Projects Networking, Protocols, and Devices

I need some help identifying serial communication between a car "head unit" and a "cd stacker".

I have just got a logic analyzer and am trying to work out the communication protocol between the 2 units, Here is photo of the pinout of the PCB:

and here is the data i have managed to capture so far:

I have never used a logic analyzer before and am having trouble figuring out what settings i should be using. Anyone able to help identifying what settings I should be using?

I am trying to replace the cd stacker with an AUX in lead and an arduino to make the head unit think the cd stacker is there (to enable the aux in)

I can't help but I reckon if you add the words "with a logic analyser" to your Title you will be much more likely to get the attention of someone who can help.

If you modify your Original Post you can edit the Title

Thanks, Done.

There are 3 types of serial communication: I2C, UART, and SPI -- which one? And what is your hardware setup between data sender and data receiver?

This is what I am trying to figure out. All I know about the "data sender" and "data receiver" is in the image in the original post.

Image result for types of serial communication
There are several types of serial communication depending on the type of transmission mode and data transfer. The transmission modes are classified as Simplex, Half Duplex and Full Duplex. Simplex Method: In simplex method either of the medium i.e sender or receiver can be active at a time. I have a Saleae and I have over 30 different protocols. Such as I2C, Manchester, SPI, 1-wire, CAN, etc. Try these links for a start but realize the serial protocol is proprietary to the vehicle manufacturer, many times they use PWM or NRZ, much easier to do with a single chip micro..
