It depends what year your Lexus is. Also, apart for the generational breakdown, there are version breakdowns, meaning you can have an older generation nav in your Lexus, but update to the newest map with updated POIs and addresses.

You can find navigation wiring diagrams for your 1998 through 2000 Lexus at most Lexus dealerships. Lexus service manuals will have the diagrams and can be found at most local libraries.
I believe the LX570, like the LS460, uses a hard drive to store the Map data and needs special equipment to load the DVD Update on to the hard disk. You probably will need a half hour installation service from your local Lexus dealer.
The 2002 Lexus radio and navigation system fuse can be found in the fuse box. The radio and navigation system fuse will be the number six fuse.
12 is allright
You can read reviews of the Lexus in-dash GPS navigation system on Amazon.com. The link for you to visit is http://www.amazon.com, and you can also order this product from this website.
The 23250-74080 part number is for the denso 312cc injector which should be stock in your car... you would be looking for a denso part number that would be wrong.... Check out sard injectors... they have a listing for a high impedance (very important) top mount denso style injector... do a search on "sard" and you will find them......
FINALLY! in MARCH 2008 Navigation Maps for Greece are here!On a telephone call today (17 MARCH 2008), I was told by Lexus customer service that the maps for Greece and some other countries is available and the Greek customers will be notified of the procedure to order and install the update in the next few days! Coverage is not yet fully defined, but I was told that the update will cover all areas already covered by NAVTECH (the company producing the software). For more info call TOYOTA HELLAS +30-210-2808000 and ask for the LEXUS customer service! Enjoy! (hope they work!) DG - Athens, Greece
