My question is...is it possible?
I've heard of people using a splitter of sorts. For reference, I have a 2009 MKV VW GTI and a Pioneer F90BT. The GTI has an integrated dual purpose powered antenna and have two wires coming from in the dash; one for the antenna and one for the Sirius. I have been told there are two ways to do this; either by the IP BUS and Sirius antenna seperately or you could somehow use the 'splitter' and combine. Anyone have any thoughts or ideas?
