Re: New member intro, some problems

["Fred Munro" <munrof@isys.ca>]

Welcome to the list, Carlyle! I am not that familiar with the radio system
(never having had a problem with it - the PO installed a Pioneer unit to
replace the failure prone OEM unit), but I recently had the centre console
out of my '91 200q and noted a couple things in passing which may apply to
your problem. The antenna leads were labelled "front" and "rear" - the Audi
OEM radios would select the antenna which gave the best reception. I would
guess that the voltage carrying "antenna" lead you have found is actually
the power lead.
