Bought a CD controller from VAIS Technology. No on screen info or steering wheel controls as the VAIS salesman told me. I called him back after install, and he told me my Ipod was too old.

I finally decided to replace Ipod - called VAIS to see if new Nano would work - he said it would, but it wouldn't charge. VAIS is coming out with an adapter this spring to allow Nano to charge. So, I bought a new Ipod instead.....now he tells me that the screen & steering controls only work with Gen 5 nav.

I am disappointed - maybe another system would have worked with my Gen.

So, can I update my Gen to Gen 5?

no can do, unless you are going to spend serious dough

Not willing to spend the cash. Will run the pod the old fashioned way. Sounds the same...I guess that's what matters most.

Thanks for the info.

You can however upgrade to a gen 4 (2004-2006). A few guys have already performed the upgrade in the GS forum, and its basically plug and play. I think the only issue was the background color was not saving, and kept reverting to the green color.

Maybe the onscreen & wheel controls will work with the Gen 4 upgrade.

Where would one buy the parts for this upgrade? Junk yard, Lexus dealers, online, etc?

Generation 4. version 8.

And if you were asking if its the same as the newer Lexus' then no, newer ones use a gen 5 system.

What does the upgrade consist of? Hardware of Software?

Will the Vais Tech iPod adapter work with Gen 4 - i.e steering wheel controls, display on screen, etc?

different layout, and maybe few newer options?? I think it's software only... I had no idea Gen3 can easily change to Gen4, thats really cool!

The Gen 5 on the newer LS460 have the "I Agree" screen disabled on versions 7.1 and above. Is this something that a newer version of the disk for Gen 4 can do also? If so, then I'll be willing to upgrade for $300 or so. Right now I have 4.1 and the manual "menu/volume/ up-down-up-down" thing works, but it's just a pain to do it when I need it.
