How to connect the video cable?
Connect it up this way on the back of the radio, it is only possible to connect one of the 2 plugs this
way. This is usually the pink plug while the purple plug connects on the screen itself. Color may vary
so do not rely on color code only.
How to connect the Bluetooth antenna?
Install the antenna on the rear shelf or C/D pillar for optimal reception
