GREAT NEWS! After alot of research and frustration regarding a direct wire installation of salellite radio in my 2001 Lexus LS430 w/Mark Lev & Nav it has been done. It does require modification to the radio wire harness which would void any warranty but works and sounds great. Clean install. My opinion is that the quality sound falls between FM and CD disc. The installation was performed in Delray Beach, FL. For those who can access this area contact Bernie @ Custom Car Works 561-279-0045.
Good Luck!
