I am the new owner of a 2006 Lexus RX400h...which I am in love with by the way. I wanted to know a few things about my navigation/GPS.
First...I have version 4.02 currently installed....I would like to upgrade to version 7.1. Do I need to stick with the same generation? I've been reading a lot about how some Gen 4 and 5 models are the same or will use the same CD's?
Second...when I do get the new upgrade how do I install it? Where is the CD drive located in my 2006 RX400h? Some have told me under the seat, some one told me in the back door panel? I've looked in the manual with no luck. Do I have to remove the panel and install it?
Any help and guidance on this matter would be extremely helpful.
Thanks!!!
