Has anyone tried it or know if navigation unit from 04+ LS is possible to put into an 01-03 LS??? Since size and appearance looks exactly identical...Only reason i would want to do this since my nav screen is going bad and it would definitely be an upgrade since 04+ has better graphics.

 

Its not possible, the gen 3 and gen 4 systems have completely different hardware

 

Someone has already done it on the GS model. All you need to do is replace the Navi ECU to a forth gen. You can read more about it in the GS forum. According to the author, its a simple plug and play.

 

Thanks man i am going to read on this

 

that would be interesting

 

I'd like to read about this too....Anyone have a link to the post ? I have been searching and reading....can't see to find it...

 

forget gen 4, how about upgrading to gen 5 with ecu update... i would love to have gen 5 on my 04 ls..

 

Just wondering what level a 01 LS430 can go, can it go to only a Gen 4 or Gen 5 ?

Would like to read it but, still can't find the info...
