• I'm using it for reverse cam as well, gear is detected

2. HDMI Adapter to charge mobile phone & convert mobile phone's resolution to CID's 420p https://www.delock.com/produkte/G_62988/technische_details.html

• if you wanted wireless mirroring, because your phone doesn't support HDMI output, then use a Miracast device instead (it connects to the video interface via HDMI as well)

• you want to charge your phone, therefore just getting USB C - HDMI cable is not enough, but would work

4. USB C extender cable 1m

5. USB C - USB A charger cable 1m
