This might be a question asked many times before and if so im sorry. I did some looking and couldn't find anything. Just got my wife a 2013 IS 250 C yesterday and have been playing around with it. The navigation says it is from 2013 so i have been trying to figure out how to update it and cant seem to find an answer. Looked through the manuals and they provided no help. I cant find an SD card anywhere or a compatible nav DVD or flash drive update that applies.

Also how do you know if it has the adaptive cruise control and some of those features? I have not gotten it to a point where I would use Cruise so it might be obvious but just trying to figure out what all this car came with.

Thanks!

 

Normally a Nav update requires a visit to the dealer.

If you have all the buttons they mention in this video you have Dynamic Cruise.

Sadly, the Nav update requires a trip to the dealer and some $$$.
