navigation update for an is 250c

[Richard Carr]

greetings fellow lovers of lexus wonders. i would appreciate some information in relation to upgrading my 2009 250 lexus convertible navigation system. I believe it is a cd disc that lives in the cd player.  Lexus Port Macquarie want to charge around $500 odd. I think it's over the top. I have seen these CDs advertised on ebay for a very good price but do not know which one is the right one. I also think, watching some you tubes that a special tool is needed to extract the disc. they look like pins . Any help, advice that you guys and girls might offer would be greatly appreciated. I currently use my iphone to navigate, but it's also nice to use the genuine article.

kind regards

Richard Carr
