I spent a lot of time at the Tesla dealership trying to decide on interior colors. While doing so I noticed the following problems with the navigation system.
1. When specifying a location for a long drive, the system only gives turn by turn directions and does not show the route on the map. I was in the Menlo Park show room and this occurred trying to navigate to either LA, Reno or New York. I actually value the map route much more than the turn by turn details. The picture of this screen shot is at the bottom of this blog post.
2. The system does not offer alternative routes like my Toyota Highlander. For example if I would like to drive to Death Valley or Las Vegas, I could go through Tehachapi or through LA. Or if trying to cross the San Francisco Bay, the best route really depends upon traffic conditions. I would like to be able to configure a through point or at a minimum be given a series of route options.
3. I could not find a single configuration button. I prefer to be able to configure items such as the voice of the person giving directions and the MPH estimate for driving distance estimate. I could not determine whether the time estimate was based upon actual traffic conditions or not.
