Tesla will soon upgrade its proprietary navigation and mapping system, called Tesla Maps, in an upcoming over-the-air software update.

Announced using tweets by Tesla CEO Elon Musk on March 3, the navigation system will feature improved navigational capabilities, on top of its vector graphics-based system that produces cleaner visuals and faster processing of information.

In the Twitter post, Elon Musk also confirmed a “major navigation overhaul “ promising a significant upgrade over the existing system, citing the project as “almost” done in response to user @ToddBourne, a Model S 100D owner who requested a fix for heavy traffic routing after depending heavily on Google Maps for a nearly-missed theater show.

In a separate post, Musk also provided a current status of faulty TuneIn radio media playback.

At the moment, many Tesla drivers continue to report issues with routing issues, with missed charging stations and low-efficiency routes, especially in high congestion areas.

No word yet on exactly when the over-the-air update will be released, other than Musk’s confirmation of “early 2018.”
