you need a gen 4 disk.....

 

very helpful
where do you order form?

 

If you look at the Lexus Navigation Chart (Link) posted above you will see that the 2004 RX uses a Generation 3 disc.

 

You can purchase the Navigation update disc from your local Lexus dealer or the CL sponsor Sewell. I see there are two discs for this 2004 RX one is marked PT219-GN23E-11 and the other is PT219-GN23W-11. (West or East???) You better check this out with Lexus before you order.

 

thanks for the correction.....I need new glasses! LOL

 

west or east?
i am on the east coast if that is what they mean...

 

No, they were wondering about the difference between the part numbers: 23E vs. 23W

Were guessing what the difference might be. Why you should ask before ordering as you might get one for the wrong region -- if that is what the reason for the difference in part numbers truly is all about.

 

Sewell would have DVD's on clearance, check them out 1st.

Or else fleabay would have them, too. Just buy the original ones. Beware.

Go to Sewell 1st and look for the closeout.
