Im having problems with the Nav screen on my 2007 IS350, I can see the L and read the agreement statement but I cannot press the accept buttom. how could I fix it?

Thank you

 

This problem has happened to a number of owners here, most frequently on '06 and '07 model year cars. It is usually the touchscreen digitizer or a related component. If the car is under warranty (or extended warranty), the dealer will probably replace the entire unit. If not, you may find an audio shop that can handle the repair.
