I am able to get my setup to work in either of these methods.
1 Sena to phone and tomtom
2 phone to sena, and tomtom

1. iphone to sena
2. tomtom to sena

What i am trying to do is have my phone button still bring up the voice control of my iphone. I would think that method 2 would work like this, but when i hit the phone button it activates the tomtom to the audio test screen. Is what I want to do possible? I have tried pairing them in different orders, but when i do the iphone second it always disconnects the headset from the tomtom. I would prefer to use the voice activation of my phone to control my phone rather than having to reach for my tomtom. From what i read in the second post on this forum http://discussions.tomtom.com/t5/RIDER/Sena-SMH-10-and-Rider-v-5/td-p/777269 he seems to have the setup, but i have been unsuccessful in re-creating that. I feel like this would be a better forum to ask if that is even possible, or should i just stick to using the tomtom hands free calling? Thanks for any assistance.
