An odd problem, yesterday evening. My BMW Navigator 5 was nicely giving me riding instructions on my Sena SMH-10 headset, but I was unable to call my wife to let her know what time I’d arrive on our meeting point. Odd, because Garmin’s SmartPhone Link icon was visible in the title bar, as was the bluetooth icon. So my phone was connected and transmitting information to the Navigator 5, but the Navigator 5 didn’t know it was a phone?

I went to check the Bluetooth setings on the Navigator. My phone was connected through Bluetooth, but the phone call functionality was unavailable. Retrying the connection would immediately fail on me.

After removing and re-establishing all Bluetooth pairings on my phone, the Navigator V and my Sena SMH-10, and even rebooting my phone and switching my SMH-10 with another SMH-10 I had laying around, I did the only other thing possible: reboot the Navigator 5.

Well, it turns out this solved the problem. Pairings were restored, and my Navigator 5 remembered again an iPhone is also for initiating and receiving voice calls.
