My Previos Cellphone finally Crapped out on me this last weekend and I went out a bought the Razr. Never had a Bluetooth phone before and the thing is amazing. Really easy to interface with the Prius (took about 2 minutes) and love not having to take my hands off the wheel to make a phone call. Now I just have to transfer each of my 200+ phone Numbers into the system. Wish You could do it all at once, but apparently you have to enter each individually.
