I believe it WOULD do that, with the proper interface cable, but you wouldn't use it that way with a Spyder. The audio input on this new unit accepts an interface cable from the bike's entertainment system - not an output to your wired headsets. You'd have to get a Bluetooth headset like the
Sena 10S. The whole idea of this unit is to get rid of your wired headset and enable the use of a BT headset.
We can do that now with the Sena SM10 Bluetooth dongle. But as Bob said, the SM10 is getting a bit dated and it would be nice to enjoy all the benefits of the newer upgraded BT protocols. As Billy said, it would really be interesting to read the manual for this unit to see what advantages we would would have when using it with a Spyder. But I'm fairly certain that using it with wired headsets is not one of them.
For most Spyder owners, this new Freewire unit would be nothing more than an upgraded SM10 - which, in itself, would be useful. However, there are some Spyder riding groups who prefer to use 2-way radios rather than Sena's multi-bike communication features. This new unit may make doing that a lot easier.
