When I asked Saris why they sent me a 2.4 head (that required a new coded strap) they told me they only make one head unit now.
Mine has 2.4 on the front and 'wired' on the side. I would doubt that it would work with the wireless hub if it says wired on it, and the emails/phone calls above tend to agree with that. But, since I haven't actually tried I'm not 100% sure.
