That is the LF-A Prototype.

I just sold my 2008 IS250 and have the updated Nav disc from Sewell that I bought mid-2012. So this is NAV disc part number PT219-GEN05-11. This disc was released at the end of 2011. The latest release is CY2012, just came out. A great way to update your nav while using an OEM disc. All original packaging included. Paid $175 at Sewell. $100 shipped via paypal obo. Compatability Guide (Model / Year): ES350 / 2007-09 GS350 / 2007-09 GS430/460 / 2007-09 GS450h / 2007 & 2009 GX470 / 2007-09 IS250/350 / 2006-09 IS F / 2008-09 RX 350 / 2007-09 RX 400h / 2007-08

Check to make sure there is no oil in the coolant!

Would be an awesome upgrade!

Highly recommend Michelin Pilot Sport A/S Plus

My 2008 was amazingly reliable. The motor oil always looked clean and never burned a drop of oil in between 5k mile oil changes

Why not compare the part number on Sewell and get a 3rd party shop to install?

I just sold my 2008 IS250 and have the 2011 map update that will work for 07-09 ES350s. Part number PT219-GEN05-11. Still have the original packaging. The latest version is CY2012.
