Interference?

[Anito]

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?

What is the exact model radio that you have? There are some who say that the phatbox will not work with the 06 model Audi.

Phat box works fine on my 06 Audi A4 (B7). With RNS-E Nav+. I needed the VW cable, instead of the Audi one. Head Unit Type T

Only problem is that mix mode turns off the minute you manually change tracks. i.e. you change a random song your not in the mood to hear.
