It's just a standardized transmission protocol, instead of every different computer having it's own special transmitter. They have to be paired with the computer.
As someone else pointed out, the Garmins are ant+ (actually ant+sport) so they should work with the speed sensor. Also you should be able to use one of the Garmin HR straps with the node.
