In a former post https://forums.swedespeed.com/showthread.php?627729-Rear-camera-through-RTI-screen&p=7655713&fbclid=IwAR0ZNSvD5b0b3WN8Q5IsMOawfpWOlNka9IQLr3x7ILXvtgg0TS_P-xvH9eo#post7655713 I explained that I had installed a NAVIKS Video Interface in my volvo C70, linked to a rear camera.
However the NAVIKS has also an HDMI Interface.
So I connected my Mobile to the NAVIKS with an USB-C --> HDMI cable,
and it works:
Sound is transmitted through a Wireless Audio Adapter (Hagibis) and commands are issued through Google Assistant/Voice
Rear camera works like a charm when the car is in R
The only small issue is that whenever I start the car again, I have to push a button to reset the NAVIKS module to the HDMI input, instead of the standard RTI image of the C70.
That button is provided by NAVIKS with a 2 m cable and allows to switch between the 3 inputs (RTI, HDMI and VIDEO 2)
Hope this can be useful to some
Next step would be to create a wireless connection with the NAVIKS instead of a wired one. Must be easy, and NAVIKS sells a Wireless module thta I haven't tested
