Upgrade 2001 LS430 Nav (gen 2) to Gen 4?
Upgrade 01 LS430 Nav to Gen 4 IT WORKS! (photos added)
I found mention of this in one thread but wanted to see if anyone here has actually done this. I have an 01 LS430 with the gen 2/3 NAv in it. Is it true that I can just swap out the Nav Disc reader in the trunk for one out of any 04-06 LS430 and use the gen 4 disc and have a complete gen 4 upgrade? Any modifications needed or just a simple plug and play? Thanks!
It works after all. So much faster than the old Nav system and more options.

nothing? lol. I know it's possible with the LX470, another reader did it, and the GS guys do it too. I'm pretty sure it's the same with the LS, just hoping to find someone to confirm it.
I've seen this done on the GS as well. It should be the exact same connectors on the LS as well. The only issue i heard of was the background color not being memorized when changed, and will revert back to the green if i'm not mistaken (on the GS.)
So it SHOULD be a straight plug and play, especially on the LS since it uses the same screen and controls.

good to hear, I'll let everyone know on Wednesday next week. I ordered a DVD player from an 06 Toyota Highlander Hybrid (same player as the 04-06 LS430) so hopefully it works. Maybe it will even come with a disc 
Stay tuned for updates.

Seems like a great deal. If you have success, I think I'll follow your lead. I'd love to get hte extra functionality of the 04 nav. Do you think the new features extend to the audio interface and features as well?

doubt it, but we'll see. i dont even know what the differences are, anyone? I know it's faster to calculate routes, newer (so I'd expect it to last a little longer than an older one), but other than that I dont know.

same question here, is it going to work with 2001 LS UL or not?
FYI:
2001- Gen 2
2002-2003 Gen 3
2004-2006 Gen 4
So yes, the one from an 06 GS or LS will work in your 01. NOW, the one from an '07 GS will NOT work, gen 5.
I'm excited now. I can't wait to see if Generation 4 works. Does Lexus still update Generation 4? I have Generation 3 NAV.
you have to buy the actually DVD player that mounts in the trunk. they can be found on ebay for about $700-900. mine should be here in the next couple of days, so I'll post an update as soon as I have tried it.
