Car Modding
I had to relocate my original Radio/CD player in the trunk and keep it set on aux input source. This included buying about 60m of wires and also harness:
1. Metra 71-9003 Bmw Mini Factory Radio OEM Wire Harness
2.Scosche VW03B 2002+ Vw Audi BMW Radio Stereo Harness

Safety:
    - The wires are 2mm in diameter with good insulation, resistant at temperature variations
    - I have added fuses(1.5A for the radio, 1A for Raspberry PI, 1A for display, 0.1A for reverse camera trigger, 0.1A for reverse camera video signal)

Bugs:
     - sound pops(will soon disappear by using this hdmi to hdmi and audio splitter)
    - Navigation is behind Video Player -> Navigation isn't visible while playing videos
