You can update the controller using the latest 1.4 file if it isn't already on 1.3.2
Or download two versions if you like, it's worth keeping old ones anyway.
I don't expect anything would go wrong if you didn't update, however the Waypoints do use C1 and C2 to set markers so that might not work on older firmware.
