You have to remove the cover under the glove box, the fuse box is on the top left (black cover).

Try passenger side, remove the glove box to access it.

Gratz on your rx350 but I think you will have problem selling it, when you said 2009 model and the entire interior is the same as 2007/2008. As you know by now that there is entirely new look 2009 RX350 (huge improvements/design). Why Lexus is going to build 2009 cars with same concept as 2007/2008 from Jan 01 till end of Feb. and unveil a new model the following month. I think you know what I'm talking about, theres something fishy about that 2009 model of yours. <_<

Maybe the hardware that should be upgraded.

NO. You can't update the map on your navigation, everytime there's a new version you have to buy the dvd (if you want to).DVD is compatible to all lexus (with nav.).
