Lexus link actually isn't discontinued, I have it in my 01 and it seems to work ok; I get an answer when I press it. Every now and then I get a call failure, depending on where I am and conditions. I guess after 2008 it'll be touch and go as analog won't be required by the FCC. Perhaps they'll have a digital upgrade.
Doesn't the 04 and the 05 SC430 come with a digital version? How hard could it be to swap it out, I can't image the actual unit being any larger than a small crcuit board.
i mean u can't purchse it anymore...but it hould still be there on cars that have it from back in the day.
i had a whole conversation about this with my dealer
