Updating Navigation System Version in 07 - 13 Lexus IS250 / IS350 / IS-F Posted May 17, 2010 Just a follow up: I just finished downloading the Nav 9.1 update (Part# 464210-1380). Burnt the disk, works perfectly. :) Hi, I just joined today and am looking to update my Nav system. Can you tell me how you got your update and at what cost. Thanks Vince
