Been looking at various posts relating to the RT3 head units in the Ulysse, but don't have a definitive answer to my question yet...

I have a 53 plate 2.0 JTD Ulysse Dynamic that has the RT3 N1 head unit (with a nice monochrome screen full of lines) and no CD changer (that I'm aware of).

Is there any simple/easy means (other than a crappy FM transmitter) of getting an AUX input into the back of the RT3?

I've heard mention of CD changers being between the front seats - could there be a wiring loom I can tap into here or am I wasting my time?

Many thanks indeed.
