I just scored this unit on amazon for $750! Amazon has an awesome return policy I could not resist! I think this unit has a good balance for what I need. I currently rely on my tomtom on my iphone 4 and this will be an easy transition. The price point, 5 second boot up, and simple interface pretty much sold me. Quick question for you Sony Nav owners, are there any speed lockouts (locking input when in motion)? If so have you figured out a way to bypass it? That was one of the main reasons I didn't go for the OEM Toyota navigation option with my trim. Thanks for pointers and can't wait to get my new Sony unit!
