i did it and it installed over the air, in my garage. anyone know what's in the update? i didn't hit 'details' when it prompted.

 

You will get these updates periodically. I've gotten probably 10 or more since purchasing mine in May 2018. Honestly I've never really noticed any difference after any on the updates. My suspicion is just very minor 'bug fixes' as they say in the APP world. At least it makes you feel like LEXUS is paying attention to us.

 

I'm guessing it is more of a data update, not a system update. Roads, conditions, boring stuff?
