I bought G2 with this adapter it did come with the first version of G2 before they went USB. I opted for this version over the transmitter that comes with it so I could use my own radios. I am not sure if you can still buy this cord from Tower I would assume you could since there are a lot of G2 owners out there with this cord. Now you may be able to get it with the USB cord instead of the parallel one.
