Guys, do the IS-F and the IS350 share the same nav disk before the went to the usb?

 

I'm pretty sure all of Lexus/Toyota products use the NAV-tech (?) brand discs. I know their are model specific, but don't think the sub model would come into play. For example a 4cyl SE Camry disc would work in a V6 XLE Camry. I think it would work from 350 to F and vice versa...

 

pattatted4 is wrong, the discs are not model specific. It goes by generation; all 2IS cars with DVD discs use GEN5 nav; and the disc from my car would work in any other GEN5 Toyota, Lexus or Scion, even hybrids like the Prius which have those funky energy monitor screens. For Lexus cars other than the 2IS, look here: http://www.lexusnavigation.com/what-to-order/

 

Isn't that what I said??? GS might not go into CT, but IS to IS should work?

 

Yes, thay all use gen 5 nav unit
