Old News - And Not the Whole Story:
LouFROM LEXUS CORPORATE:
Errant data broadcast by our traffic and weather data service provider was not handled as expected by the microcomputer in the vehicle navigation head unit (center display) of 2014-16 model year Lexus vehicles. In some situations, this issue can cause the head unit restart repeatedly, affecting operation of the navigation system (if equipped), audio and climate control features. The data suspected to be the source of the error was corrected last night.
The correction is a forced reset and clearing of the errant data from the system. Disconnecting the vehicle 12V battery for at least 5 minutes and then re-connecting the battery completes this reset.
Lexus owners experiencing these issues should visit their dealer for a complimentary system reset and a confirmation of the system
Thank you for your patience and on-going support.[/B]
