So I've downloaded Navcoder (thanks Jochen!), and have bought myself an Ibus /RS232 interface card (from Mr Resler), now all I need to do is try and hook it up to the Ibus.

I have searched thru here and it seems the easiest place is "on the CD changer".. however for those of us that are electrically challenged,..does that mean I unplug from the CD and can plug into the pins on my interface card.. or do I have to splice wires etc?...
I guess I have to remove the CD player as well?

Any pointers would be much appreciated.
