Hi lexus7782,
I found your post about installing a double din navigation system on 2003 Lexus ES 300 very useful. I have the same car model and am thinking about installing a "Kenwood Double Din DVD Nav DNX8120" in my car.
I will be grateful if you can post or send me picture(s) post installation. I quite keen to see how it looks. Thanks a lot!
Regards
Gaurav
