BlueSonic > Zumo550 > Nokia 5500 Sport

The parring whit the Zumo 550 run easy.
You can set Nokia 5500 direct to Zumo, and then connect Bluesonic to Zumo as a headset, then it´s the control from Zumo there handel the phone, white voicecall, touchpad. - And the Navigation sound runs then the phone are standby

Thanks, I sold my 550 and is waiting for the 660, hopefully that will work the same way, I tried with Nuvi 765t but it does not seem to have any headset-profile for bluetooth, only Phone and Audio-device.
