Hi!
I’m planning to create an integrated solution for my Volvo V60 Polestar MY2018.
The interior (esp. the factory Sensus Connect infotainment 7" display) looks like this:
Components I’m going to use:
IndiWork HD-LINK IW03V-N23 (for Volvo)
Link: http://indiwork.co.kr/shop/hd-link/hd-link-iw03v-n23-for-volvo-gvif-3pin/
This device has 2 HDMI inputs which the factory display can be switched between.
Most likely I’m going to use an AutoPi and a Chromecast (or maybe an Amazon Fire TV stick) 
The Sensus 7" display has a resolution of 800x480, it seems. That resolution is said to be supported by the RPi as well.
AutoPi special configuration package
I want to use a Raspberry Pi 3 B using the offered adapter instead of the Pi Zero in order to have lots of power reserve for everything I could try
Also, I want to use it with an LTE Advanced Cat. 6 modem (which also supplies GPS functionality) instead of the currently offered LTE modem.
I’d also like to use a molded case that fits the AutoPi including the RPi3. AutoPi staff told me that they consider offering this
The AutoPi will be connected to the NAVI input HD-LINK box (which is HDMI).
Chromecast or Fire TV stick
The Chromecast or Fire TV stick ill be connected to the other HDMI port of the HD-LINK box.
This solution is going to replace my current setup consisting of a ScanTool OBDLink MX Bluetooth, my Pixel 2 XL smartphone and the Android App “Torque” which I use to monitor OBD/sensor data while driving (especially lambda, fuel trims etc.).
Unfortunately, my car lacks an oil temperature sensor. If I find a good location on the engine block to put an add-on oil temperature sensor, I’d like to connect it to the AutoPi as well.
Cheers,
Wolfram
