K McCarthy

Hi all, I recently bought a 2005 CL 600 and have been getting to know it. I have found that it has a built in radar detector which announces with a less than charming disembodied voice things like "k-band ahead" or "red light camera ahead". It also turns the indicator light next to the left side Parktronic indicator red. I don't see anything in the owners manual about this, does anybody know about it and how to turn it off? Thanks!
