I believe you have to enter a code in the sound system to get the nav system to work. Not familar with Lexus nav system, but I do think it has a lock out feature to prevent theft. You need to find a Lexus friendly tech that is familar with the nav system. Hopefully one of the techs that give answers will know what to do. Good luck
thank you so much.

You can remove the battery. It won't affect the Navi system. You probably had other problem.
