RX300 Navigation CD- latest
 

I have a 2002 RX300 and I need to get the latest Navigation DVD (2009) but I don't know if there is one available for my car's year. Can someone tell me where to get it and if it will be compatible? Also, I have the voice navigation DVD now (I'm assuming they are all voice navigation DVDs) but I want to make sure. Any suggestions? Thanks! Sarah
