I'm thinking about replacing my 1999 RX (230K) with a 2002-03. Is the Nav system worth limiting my search in order to get? And, was the Nakamichi stereo still available? (I have it in my 99, and it is great.) TIA.

 

while the NAV is useful to have, if i recall the DVD updates that were compatible with the included unit stopped at 2004 if that is a make it or break it for you.

 

Nakamichi was not available in 2002 and 2003 years. 2001 was the last year it was offered on the RX300.
