SMH10 can wirelessly connect to other Bluetooth devices supporting HSP/HFP (Headset Profile/Hands Free Profile) and A2DP (Advance Audio Distribution Profile). HSP/HFP is standard in all phones with Bluetooth feature. Almost all Bluetooth MP3 players, Smartphone, audio dongles support A2DP to send stereo audio to Bluetooth headset like SMH10.
As for GPS navigation system, Sena highly recommends GPS navigation system designed specifically for motorcycle. There are many automobile GPS navigation systems which support HSF/HFP, but many are only able to connect to Bluetooth phones and will not work with Bluetooth Headsets
