I have a 2004 RX330 and have had no problems with my navagation until a few days ago. I get a message saying "unable to read data. Check if map DVD is correct" Has anyone had this problem? Where am I supposed to check for this DVD?

 

the dvd disc is in the trunk. if you life up the trunk mat, on the middle area, there should be a handle. open the latch, and on the right hand side, you should see a plastic covering that covers the dvd player for the nav.

 

thank you sooo much! I reinserted the DVD and now the navigation works again.

 

If you haven't updated your disc yet, the 2008 Nav disc for the '04 RX330 with the GEN3 navigation should be available in August or September. I work for the company that supplies them.

 

Any word on a possible unlocking of the nav while in motion for the new version?
