Did you have to plug in anything to the headunit BESIDES the plug?
Are you saying the radio without the NAV, does not have the a CD button? It requires the plug for the external CD changer, that's where the Phatbox plugs into.
The only reason I say it's compatible with our NAV unit is because the Trafficpro is a Nav unit as well.
There is nothing else to plug in. BTW, here a demo on how it works.
