Regarding the issue of not being able to place calls while the car is in motion, I have two suggestions:
1. This is a lousy work-around, but you can always pick up the phone and dial your number. The call will go through and will be through the car's speakers.
2. You ~are~ able to place "One Touch" calls through the car, even while moving, if you have set them up.
That said, I think the only way to set up the "One Touch" dialing is to have already set up the phonebook. See my previous post for suggestions on how to set up the phonebook by using a different cell phone. Once the phonebook is set up using a separate bluetooth cell phone, it will work fine for your v710. However, there is a 17 phone number limit in the "One Touch" system. For me, this accounts for 90% of my calls.
Also, for what it is worth, I spoke with an aftermarket stereo/DVD installer regarding my LX470, and they indicated that they were able to bypass the Lexus speed sensor/parking brake sensors so that the Nav and Phone systems will work while moving. They indicated that it will likely invalidate my warranty on the electronics, but it might be worth it.
Now a question: Has anyone figured out if it is possible to set up voice dialing through the car?
