Hey guy, I just bought my 02 IS300 and it still has the factory 6 CD radio. I've done some searching and all the DIYs are for 2001s with an AVIC radio. Are these the only ones we can install? And what is different from 2001 to the rest that I should know? IF there is a diy for 2002s with any double din could someone link me up? I hate to pest, but I tried searching on multiple forums.

Thanks guys!
