Hi,
I have 2004 RX330 and I just bought a new Lexus/Toyota Nav ver 5.1 DVD off ebay. The seller seems legit and have positive responces from others that bought the dvd. Also, the dvd looks genuine.

I installed the DVD in the trunk and my nav says "unable to read data, check if nav dvd is correct." I tried it multiple times and still the same result. If I reinstall my old 3.1 dvd, it works fine.
Finally, when i got the dvd, there were some small fine scratches on the image surface. Could this be causing the problem? Did I get screwed with a fake? Is my 2004 rx330 not upgradable to ver 5.1?
This has been very frustrating. :cries: Any help would be greatly appreciated.
