To install the JVC KD-R711E car radio with Bluetooth and USB in Polo N9 this adapter plug was used. The first direct cobbling together existing plug the radio did not turn on. When printing on the CD-Auewurftaste the illumination of the radio went on briefly, but then it was all over again. A search on the Internet led to the solution of the problem: red switch with yellow Anschluskabel. I have the cable pinched off and reversed again soldered together and pulled a shrink tube. After installation, the radio was as expected.
