6.4.2 GPS Pairing as Mobile Phone
If GPS is not only used for turn-by-turn voice instructions
but also is your preferred Bluetooth stereo music source,
you can pair the GPS to the SPH10H-FM by following
the simple procedures in “6.1 Mobile Phone Pairing”.
When you do this, the SPH10H-FM thinks the GPS is a
mobile phone. But the SPH10H-FM can directly pair an
additional mobile phone.

Note:
You have to use a motorcycle specific GPS which transmits
turn-by-turn voice instruction to the headset by Bluetooth.
Most automotive GPS systems don’t have this feature.
