    Why doesn't the NAV system work while you are driving? Is there a way around it??

    For safety reasons Toyota does not want you concentrating on the Nav screen rather than focusing on the road ahead. At first I was not sure I understood this but after all of the media hysteria, claims and lawsuits against Toyota for a lot of driver error allogations, I certainly understand now.

    There are two work-arounds. 1) Plan your trip ahead of time and map it out before you leave or 2) Use the Voice Commands while driving.

    For your information, in the European Prius the Nav System is free to operate while driving.

    This seems to be a common feature for American NAV systems. Even the stand alone models do this - my husband's Tom Tom reacts the same way.

    I actually prefer this safety feature - it provides one less distraction to drivers. I've already been hit by someone who was texting while driving!

    There are several ways around it - check these threads: (Warning; they are LONG)

    If you're an electronics hobbyist, here's a relatively easy circuit that will do it. The reminder of how/where to connect is elsewhere in the same thread:

    If you'd prefer a plug-and-play unit, here's an option:

    BTW, there is no software or DVD "hack" at this point, for this NAV. Hardware solution only.

    Enjoy..
