Has anyone here ever installed an aftermarket touchscreen android head unit into a X300?
Various units are offered on ebay from manufactures such as Joying, Atoto, and etc in sizes ranging from 7" to 10" touchscreen displays.
There are single DIN units as well as dual DIN units. There are also units offered where either the main head unit can be mounted remotely from the screen itself or other ones where there actually is no DIN body on the back of the radio (see photos below)

I am wondering how to install this type of aftermarket radio into an X300 dash.

9inch Android head unit with single DIN sized box

 

The X300 stereo head has 2 types of speaker output so the car side of the wiring is dependent on the option it came with , standard or premium

The difference is the car side wiring as the speaker wires start from the front dash or the trunk

The same control head and rear of the control head connector is used on both the standard and premium setup

The difference is the speaker output using a multi wire round ( tan colored ) cable to a trunk mounted final amplifier

The rear of the stereo head connector is after the output signals have passed through 2 internally final amplifiers ( Toshiba # TA8221 or the compliment twin )

Someone has already decoded the 8 wire round tan cable to the trunk final amplifier



You can intercept the the weak audio signal going into the Tashibas

OK, interesting but what are the Tele connections at 14, 15, and 16?
And what is the Spd connection at 12 ?

 

3 and 4 are the lights in the head unit

14 , 15 , 16 are a separate telephone unit

12 is a car speed sensor to increase volume with wind noise

There should be more information in the X308 area as the head unit is a similar Alpine unit and someone installed a single DIN for a backup camera

I can't find it how but here is a pic of the round tan wire bundle on my laptop ( looks like a round coax cable that may not be installed on your car but avail at the salvage yard )

I can't say if the pic is accurate as I didn't do the modification

 

Just to be clear at this point I am slightly less concerned about the wiring connections than I am about how to mount one of these 7", 8" 9" or 10" touchscreens on the dash without obscuring some other component.
