I got ES330 and the repair manual for it. Found many connectors are unused on Navigation/Radio/CD combo, I believe some of them are for RGB control and inputs...

Who made this for Lexus? Maybe I can found more pin-out info from the manufacturor...

 

denso made the previous models of lexus nav units but i heard that they were getrting out of the nav business. i havent seen the rx330 nav unit up close yet.

 

That would be Denso.

 

You guy are right, I have checked their web, it is Denso...now, the question how is possible to get more information about it? Any service manual, circuit diagram that I can order/download? Thanks..

 

Denso has contracted with a company Fujitsu Ten. I believe they make Eclipse stereos.

 

Yep, my Eclipse aftermarket Nav looks almost just like the new Lexus Nav.

 

the company who oversees JBL/Levinson/Infinity/Harmon Kardon is the manufacturer of your Navi in your ES. The same unit is found in the Camry, Solara, 4Runner and etc.

 

GREAT, THE OVERSEER COMPANY . DO YOU HAVE THE OVERSEER COMPANIES EMAIL ADDRESS. SOME SORT OF JAPANESE ELECTRONICS GURU.

 

I believe the Kenwood KNA-DV2100 navigation system is also made by Denso. At least the user interface is very much the same, indicating they use the same base program. While it won't be identical to the Lexus navigation hardware there is a service manual available for the KNADV2100 from www.pacparts.com. Search on product: Kenwood and model #: KNADV2100.

If you simply need the connectors and wires going to the navigation system look to purchase the Electrical Wiring Diagram (EWD) for your car - directly from Lexus or Lexus Dealer (like www.lexus-parts.com).

 

I don't know who makes it but you guys are talking different companies. Harmon Intl. owns H-K, JBL, ML, et al. That is not related to Denso or Fujitsu Ten (Eclipse).

 

you have any pics, how do you like the unit
