Hello!
Last year I had an issue with an Android headunit not playing sound at all. Well, that was because my Peugeot 407 is built with a stock JBL sound system, amplifier and subwoofer.
So I needed a special harness to grab power signal from the original radio and turn on the ampflier to play whatever I wanted to play on the radio - FM radio, mp3 files, youtube videos, and so on.
Now, that headunit doesn't have a fast CPU neither 4G mobile data for easy internet on the spot without using my smartphone as a hotspot. So I thought about upgrading it to a better model and use this current Android in my wife's Peugeot 307 (only need the canbus, cable and frame, and these are fairly easy to get). And her car doesn't have an amplifier, so...
So I bought a new Android, this time a Tesla style vertical screen with an 8 core CPU and 4G. I made sure to ask the seller if it was compatible with a 407 with JBL amplifier, and they told me yes.
Honestly, the sound is actually great, better than the other headunit. I can feel the subwoofer better at low volume levels, and the whole volume is more gradual. Anyway, my problem is only the radio actually plays sound. Youtube videos and mp3 files do not play. I mean, with an external speaker through the RCA outputs, it plays.
After a carefull check on the harness and cables they provided, I noticed they arranjed the wires in a strange way.

As you can see, the black power connector on the back of the Android headunit, a blue wire comes out and splits into two blue wires: one into the +12v remote, and another to the JBL amp wire. It should work, right? But that blue wire comes out from the ANT wire, the antenna. So only the radio action actually turns on the amplifier.
According to an internet search, I know I must connect the red ACC wire to the AMP wire?
Anyway I tested a few configurations by now, and none will trigger the amplifier to turn on if not the radio.
Note 1: the black power connector has a red ACC wire coming out of it, it goes into the canbus box, not to the harness.
Note 2: that AMP wire coming out of the white connector on the back of the Android, is loose and doesn't connect anywhere.
Note 3: one of the experiences I did, was to cut that blue wire going into the JBL amp pin of the harness. Even with that wire cut from the rest, it still works to play sound from the radio, so there is something else providing the power on signal to the amp.
Note 4: I'm currently exchanging messages with the seller; altough they are not being too helpfull, they end up replying my messages with a vague attempt to help; thats why I'm helping myself through internet, videos, and wiring information.
I'll accept suggestions on what wire I must connect to where.
