Maybe that addon will be an ethernet remote head like a Flex radio and Maestro.The price is in line with what I expected to see, so that's good. Looks like it implements a "one cord solution" for GPS, which I like as well. No remote head is mentioned, which is disappointing. However, looks like we may see an add-on accessory at a later date. I would have preferred a detachable faceplate/remote head, but a separate purchase remote head (should that be offered) isn't a bad alternative.
