It plugs inline on your antenna cable. You change the radio station to the preset channel and it will play the auxillary plugged into it over the radio frequency. There are some wireless versions out there, but from what I've seen, they don't work as great.
An inline version will require 2 antenna adapters on the G35. Nissans and Infinitis use a 2 prong antenna. RF modulators use a standard single prong. So you would need an adapter to convert the dual prong to single and attach to the RF, and then a single to dual to attach the RF to the radio. It might be possible to find a RF modulator adapter as well. I haven't searched much on that, but it might be out there.
