I also have a question about the DVD navigation system. I 'm not sure which one I have. I have a 2001 RX300 with original navigation DVD. I purchased the DATA ver 03.1 on ebay because the dealer price was outrageous, and now I can't seem to figure out how to install it or if this is the most current one. I've looked beside the spare and see where it is suppose to go but I don't see a way to open it. Any suggestions?
