I have a 2002 LS430. What i want to know is
1) What generation am i ? --- I am guessing i am Gen 3
2) What Navigation DVD do i need to get to update the Maps.
Will the "Toyota Lexus Navigation DVD Gen 3 v6.1 86271-33035 464210-0750" work?
will the "Lexus-Toyota USA-CAN. Nav DVD Gen 4 Ver. 6.1 - 464210-0780" work?

 

You are Gen 2/3. You need to ensure that you get the update disk for Gen 3 - and not Gen 4. Gen 4 will not work in your car, even if it's cheaper!

 

so which one of those do i need?

 

You need Gen 2/3 and version 7.1 has been released. I ordered one two days ago.

 

Thanks guys, i just did the upgrade and what do you know... It worked. BTW, i had v1.0. The wife will give it a test tomorrow.

 

Where can I purchase the DVD Nav upgrade? I also have a 2002 LS 430. Doyo uhave to purchase from Lexus?
