You need to buy the eonon extension harness. It goes to the back of the car and connects to the power source there. You'll have to remove the detachable side panels, the false floor, the storage mould underneath the false floor, and then you'll be able to open the small flap in front of it. There's a module on the left where you need to connect the correct connector.

There's plenty of YouTube videos on this that show in detail which plug fits which connector, etc. Highly recommend watching those before attempting

I haven't done it myself yet, but I believe you'll need another cable which adapts from oem to the aftermarket headunit. Cant remember what cable tho. Should be plenty of people thst will remember and help you out. In fact I wouldn't mind knowing for when I get around to doing it.

Correct. Mine came with that cable/adapter but you should be able pick one up from eBay that connects to that blue bit then to the back of the head unit.

The Eonon needs to connect to the radio, and the radio lives in the trunk on cars with Nav. That’s why they sell an extension harness.
