Listening to Iphone music through bluetooth with GPS unit

[cestep6]

Hello Folks,

I have an Iphone 4 and a Bluetooth enabled GPS (TomTom 630), and I'm trying to listen to music through the GPS connected to my AUX jack on my M/C. This would allow me to listen to an audio book and still get directions.

The GPS finds the Iphone, but only allows handsfree calling. The Iphone doesn't give me the option of directing the output to the GPS the way it does with my Bluetooth headset. I'm thinking of upgrading the Garmin Zumo 665, which according to their website has this feature.

Has anyone else had this issue? If so how did you solve it?

Thanks,

Cestep6

It depends on how the GPS presents itself over Bluetooth. The GPS is probably using the Headset profile, which has minimal controls including the ability to ring, answer a call, hang up and adjust the volume.

A stereo Bluetooth headset will use A2DP (Advanced Audio Distribution Profile). This has higher quality audio, etc.
