I was able to get my old RAZR to send the entire phone book at once.
1. Establish connection by finding Razr with AVIC.
2. Disconnect
3. Go to the add device screen on the AVIC and choose pair phone.
4. Go to Razr and search devices.
5. Go to AVIC and hit phone book transfer
6. Wait awhile
I may have goofed this up a little bit- but I got it to send my whole phone book this morning. Very cool- as the last few times a tried I could not figure it out. I had to send them individually on my last Pioneer HU from the Razr and was hoping the above worked to avoid sending 200 names and numbers.
