Installed a D+P in the V50 using the 9V connector method described on here. Sound quality is ok, a little bit of static in the background is audible between tracks but I'm happy enough.<p>But... I unplugged the antenna lead from the "brain" to see what the difference was between wired and wireless transmission and there was no difference at all. Shouldn't plugging the antenna lead into the brain disable the FM transmitter? Checked by tuning into the same frequency from another car while the D+P was playing and sure enough, it's transmitting, even with the antenna lead plugged in.<p>Any ideas? I'm off to remove all of my boot lining again to see if there's anything obvious but, short of a 9V connector having fallen off, I'm a bit stumped. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0">

Even More Confused Now

OK, so today's lesson is : Never do any wiring work without the use of a multimeter.<p>One of my Motorola -> 9V connector leads had a dodgy capacitor in the plug so the centre wire was dead<p>The other one had flaky continuity between the brass tab on the back of the 9V plug (where the wire was soldered), and the plug itself.<p>Fixed these and connected everything up again. There's now a definite click through the speakers when you plug and unplug the antenna lead from the D+P brain.<p>But...<p>There's still a fair bit of background noise, even with the ignition off. Turned the iPod up so that the HU can run at a lower volume but the noise is still there.<p>The unit is still transmitting the FM frequency wirelessly, so other receivers can pick it up and I still can't really tell whether what I'm hearing is a wired or wireless signal.<p> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/confused.gif" BORDER="0">
