Brett in AK Do you need help with a Gen 4 v7.1? Thank you for your time.

Great Idea!

I have a 2003 Lexus LS430 and am also looking for an upgrade DVD. Please contact me at flexman77@yahoo.com. Thanks. I have a 2002 SC430 that I purchased last week but it doesn't have a navigation cd. I went to Lexus yesterday and they wanted $300 for it. I need to purchase & would appreciate it if someone could contact me regarding a purchase, was hoping that Tony might be able to sell me one or someone else out there?? Thanks, melissavac7811@aol.com email sent

==================================== TODAY I purchased an 02 sc430 and noticed the nav didn't have correct I95 exit numbers in Florida - what disk can I purchase to upgrade to best most recent improved version? Is it a simple DVD swap or must deal adjust something? I can help with v7.1 in Gen 3, 4 or 5 I will check this forum more regularly.

It appears the link is no longer available

The two cars have different gen systems and so the discs are not interchangeable. Also, the gen4 system found in your 05SC will still display the I Agree message even though you upgrade to 7.1. Step Hen is correct, you have 2 different units, gen 4 & gen 5 discs are not interchangeable

http://shop.3bspecialties.com/main.sc These guys are excellent and very fast and reliable. I have bought dozens of kits for Toyota, Lexus & Scion for both headlights and foglight conversions. Never a problem. My two cents T

I need the new disc for my Lexus 2002 430 SC and this appears to be the correct part #. Can you let me know how I can get a copy from you? I am located in Dallas, Tx. email sent

http://www.clublexus.com/forums/showthread.php?t=364641 The link is the second thread you posted. The original poster didn't fully test the system out, and he only saw the new map data and never tried to fully enter in a destination. A 7.1/4.2 disc won't let you navigate anywhere, which defeats the purpose. Read the thread to the last page where others test it out and find the fault, which the OP admits to as well. I realize that, I'm saying it worked for me in my wifes 06 SC430. I will check the files but the last disc I burned was v7.1 not v6.1. Either way my apologies.

Yes you can, you use version 4.2 GEN 4 and these files INDEXDAT.KWI, LOADING.KWI, 05.CMP and IDX folder files then add the rest from the latest version.
