Doesn't work. Serial is correct. But I made another mistake - Radio has JVC Label not Becker but it's similar to Becker 4720. Same System, same Navi software.
Side of main unit says what I posted first and test screen says what was posted afterwards, But its the same request. Stupidity first. I'm no trader or dealer.
Got already the code from a nicer person than you xxxx. CODE 51133
The side of the main unit indicates what I posted first and the test screen indicates what was posted later, but it is the same request. The stupidity first. I am neither a trader nor a reseller. ================ In this case you are only a thief
