I don't think you need anything else :hmmmm2: I believe it will plug into both im sure someone else will chime in on this I had mine installed so im not too sure
Cool thanks...I have a Garmin so i dont really need to even use the navigation, but do you know can the 5510 use the sirius traffic as an addon? If the major differences are the # of slots and I-pod, I could go with the 5510 and save some cash.
