I cannot get my S3 to play navigation prompts through my Scala headset. It works fine with phone calls but the navigation prompts still play through the phone speaker. I do not plan to take/make calls while riding. I only want to hear the navigation prompts. Has anyone solved this problem?
There are two different profiles to connect a phone to a blue tooth headset - audio and phone.
When I first tried my Sony phone with my headset I got what you are getting because it use the phone profile by default. If it used the audio profile to connect it I got everything through the headset.
I do not have my Scala any more but it wasn't the set up on there, it was the set up on my phone that made the difference. Try having a music player open when you're first pairing them and maybe it will switch to the audio profile for you. That was the trick that worked for me.
