Hi Phathom,

I have been considering the Eonon D5166U unit for quite some time. My existing factory NAV screen is still in great shape and I do my AUX In audio and BT audio with a Mediabridge Unit (formerly Dice).

I have seen a camera power workaround which uses the PDC circuit to activate the camera through a relay. Here is the text verbatim:

the PDC module is located under the spare tire in the battery compartment, next to the BM radio, and it has 3 plugs. The middle plug has multiple pins, and the Pin #7 supplies signal voltage to the green light in the front of the car in the button module in the center console. When PDC is engaged, the green light on the PDC button lights up via Pin #7 on the middle plug - the voltage and amperage are very low, and that pin supplies (+) voltage. On the PDC module, there are three plugs, pin #7 from the MIDDLE plug, it is black. If you will take that (+) signal and convert it via a low voltage/low amperage relay to a (-) ground, and apply that (-) signal to the wire for the reverse signal, you will have the reverse camera engaging everytime when the PDC is engaged. It also will give you an ability to activate the camera by pressing the PDC button on the center console switch panel(module A169).

This will be my plan when I tackle an Eonon and camera install, which has a nice side benefit of camera activation with PDC button push at console.

Mike
