Hello,
i'm a ´06 Pacific owner in germany and i hope my english is to understand.
I bought an Joying aftermarket radio and a Axxess / Metra CHTO-02 for my Paci and it worked very fine with the factory amp.
But the Joying software and WiFi module was terrible and i decided to change the radio.
I wiring all the cables to the harness like the Joying and now i have only sound in the front.
The fader from the headunit still working to left and right but front and rear sounds like the same channel.
The potentiometer from the CHTO-02 does not solve the problem.
I am desperate please help me
