How did you connect the new radio? Did you use an aftermarket wire harness? Did you splice wires?

I connected as follows:

Power in put DVD unit from original harness. A1, A3, A24.
Sounds signal from DVD unit connected to amply and then connected to A15, A16, A19, A20. Others wires was correct connecting
Before connected, I checked A3. The Voltmeter indicated 12.17 Volt.
After disconnected, I checked A3 again , the voltmeter indicated 0 volt

A little investigation is saying you’re not from the US/Canada? Let me know if that incorrect. I’ve seen others say the wiring is different in other countries. Most of the users are from the US/Canada here.

I don’t know what version you have. Do any companies in your country make plug and play wire harnesses so you don’t have to cut anything?
