I have a problem with the sound in the car. Nothing works, radio, navi, warnings, PDC. The sound works randomly, it works for 1 hour and then there is silence for a 1-2 days. The same thing over and over again, there is a sound and in a moment it is gone. Everything works except for the sound in the car. There are no errors when I connect inpa. Anyone have any ideas?

Do you know which of the three common types of sound system's
you have? We are not talking about the Head Unit but two of them
have and amplifier and different speaker setups.

If you have one of the types with an amplifier I would start by checking that there
is no water in the amp area as this is a common problem.
