No audio after disconnect the amplifier.......

[vidarsta]

Today I mounted a new tow-bar to my Thesis. I had to remove the rear bumper, and also the stereo-amplifier in the trunk.
After everything was mounted back, the sound is disappeared. Try to reset the CD-changer and the Connect box, but still no sound. All fuses OK. Checked the socket and connections several times......
Anyone who has a suggestion ?

Everything OK now. Minor problem in connector-socket.......
