Can't get aftermarket radio to turn on

[sheck wes]

Hello all,

I have bought a aftermarket radio for my Toyota Aygo and am trying to install it now. My Aygo comes stock with a so called Quadlock connector and my new radio comes with a 16 pin. To use the radio I have to use two adapters which both seem to work. To start off I tested the constant 12v, ACC wire and ground with a multimeter, all work according.

Now when I try to power the radio it won’t turn on. I have tested the radio in a friend’s car and it works perfect so it can’t be the radio or the fuse that’s blown.

On the picture you can see the bottom left 8pin connector has a blue 12v, white ACC, brown (ground?), white/black (ground?)

The only suspicious things I find are that the ACC is at 10v and both the brown and white/black seem to work as ground.

Is anyone able to help me out? Thanks in advance.
