Hi there,
About to fit an aerial booster to my VW Passat (1999).
The factory fitted blaupunkt radio is about to be replaced by a pioneer head unit ( as the factory stereo needs a key card much like a sky smart card).
Anyhow, removed the factory radio and found the two plugs (yes I have a harness to convert these two plugs to my new head unit)...however I noticed the aerial cable has a band expander fitted (inline)....BUT a small black wire runs from this band expander to one of the pins on the factory plugs. Am I correct to assume this is the ground for the band expander???
Can I plug the aerial booster in before the band expander and then use them together??
Ive been told to remove the band expander and just use the booster....but what would I do with this black wire?
Id say it would be ok to 'chop and terminiate it' (and yes id leave sufficent length if I ever needed it again).
Thoughts?
