I received a message on my Nav stating that a mandatory update was available on Sunday. I performed the update but still have no way of knowing what it was for. Did anyone else see this? Also does anyone know what was updated? I checked the Lexus Drivers site and could not find anything there either.

 

I received the Lexus Enform Suite Update last Sunday on my 2015 GS , is that what you're talking about? NAV data doesn't update OTA, you need to go to dealer for that.
Not really sure what the Enform update entails..looking for it myself.

 

Got it. Installed it. Have no idea what it was for.

 

Maybe iOS 11 support??

 

Yes it was not a Nav update. I was referring to to the message that appeared on the Nav screen. I wish they would let us know what is being updated.

 

Probably just bug fixes for the Lexus Enform apps
