Hi everybody out there!

I have a Audi A6 from 2004. I have a really strange problem with my car.
The radio is dead, But the fuse no.37 is ok!

1. Measured the 12v wire (red/yellow) at the radio , there was only 0,3v!
2.Measured 0,3v at the red/yellow wire at the consert subwoofer in the trunk.
3.Measured on the red/yellow wire after the no.37 fuse. 12v ok!


My question. there must be a junction someware that will divide the cable from the fuse to the radio and subwoofer. I think that the problem can be located there? Or does somebody now if there is any other possible thing to look at?

Thanks in advance!

Best regards
