Tested built in IR receiver and to a big surprise it can receive signal despite of being behind TV and looking towards the wall.

Also tested with eMMC version of CM4 for flashing.
To enter eMMC programming mode:
- USB multiplexer selector switch to USB-C position
- Press and hold User Button
- Connect USB-C cable
- Release User Button
- Follow software procedure
Still have to think how and where to fit connector or solder pads for Ambilight...
