Hello Again,
I'm noticing that when the DMS is inserted into the keg and power is sent to the HU I get a brief series of background bleeps through the car speakers almost like there is some interferrence.
If I remove the DMS the noise goes away. I know subs kick out a lot of interferrence and I assume that as a hard disk spins it letting some off too.
I have an Audi S4 fitted with Bose + satav.
Could this be a pahtbox issue or something completely unrelated?
