Take a look at Tesla's current map UI and the new (upcoming) UI with side-by-side, simultaneous video and audio feeds.
We recently reported that Tesla was updating its mapping and navigation software, as well as looking to MapBox and Valhalla for open source support. Tesla began updating its fleet in Taiwan, and some of the first Model 3s also have the new UI, but otherwise it's not available yet.
As you can clearly see, at times the Tesla maps displays is quite different.
This YouTuber (greentheonly) does an impressive job showing the same trip with both UIs showing at the same time, and he even has the audio for each UI in opposite speakers. It paints a very clear picture as to the similarities and differences between the two engines.
One of the most obvious changes is shown on the picture to the right. On the current system, a "picture" is shown of the actual road and exit signs, whereas the new UI just sticks to the map of the area. The current system displays these virtual pictures prior to an upcoming action. According to Electrek, the new systems' maps have also been updated from 2015 to 2017 versions. The updated maps show more street names, landmarks, and details than the previous set.
The YouTuber explains that the new system's routes seem to mirror that of Google Maps. However, he writes that though the new UI follows Google Map's routing, it's not necessarily always the best choice. Keep in mind that this is based on a single route, and early on, so much could change as the new engine rolls out.
Video Description via greentheonly on YouTube:
This is side to side comparison between current Tesla UI for navigation vs the upcoming version (also currently present in Taiwan).
Left side has current UI, right side has new UI.
Additionally left audio channel is for current UI and right audio channel is for new UI.
The dashcam video is from new UI test so they match exactly, the current UI might not totally match the situation at times, but should not deviate more than 10 seconds either way.
At the end of video you can see new and old map engines disagree how to get to that Walmart. New engine selects the route that google maps would choose, but it is in fact a longer less suitable route than the one I am taking and that the old maps are suggesting.
