Just finished my install. Below is a simple breakdown of my setup:
Dash Kits:
H0017AG920 - JDM Single Din Cubby Kit
H6217AG911 - JDM Double Din Kit (w/ i88 and i85 adapters)
Electronics:
Sony XAV-AX8000 Double Din halo style stereo (Single DIN install)
Generic 7" Double Din Android stereo (Used only as a screen for BtSsm)
Metra ASWC-1
VAG-COM KKL USB OBD2 Cable
Android Software:
BtSsm (Gauges Displayed: Boost, IAM, AFR, Coolant Temp, Fuel Correction, FLKC, FKC, Batt)
Autostart and StaY! (Runs BtSsm on Android boot)
* Winter wheels don't have TMPSs installed
* Cubby info screen isn't plugged in. The OEM Nav loom doesn't have the plug for it. May install something more interesting there in the future
