Hello everyone.

I bought a navigation from Lexus IS 2009, I began the installation with the help of a great post https://www.clublexus.com/forums/is-...avigation.html.
Everything was going great until rewrite the J54 connector in the connector J53. It turned out that navigation in 2009 has a 18-pin connector (j54 14-pin, j53 12-pin). Does anyone have handled with this problem, or has the connection diagram (from service manual or techinfo.toyota.com) of this 18-pin connector?

Below is a picture of my navigation with marked 18-pin connector.

You don't need to rewire the J54/J53 at all, just swap out the whole clock assembly and your problem is gone.

From standard 2006 radio reciver? How I can do that?

I have a 2007 complete navi with ML for sale.

I know you probably don't need it now but just sending a photo .It might help.Good luck!

oh sorry didnt read that you had a non nav is250. I thought you're going from 06/08 Nav to 09 Nav. In this case you need to rewire the J54/J53, sorry for confusing you. I did the retrofit of 09 Navi into my Non-nav 08 IS but i dont remeber which wires go where since i did it like 4 years ago. Since then i got rid of the 09 unit and currently have the 08 unit. But if you have the diagrams they're fairly easy to follow, plus there's not much difference between 06/08 and 09 units in terms of wiring.
