Just was wondering if anyone had the same problem as me. My navigation/dispay screen will turn on and then freeze after about 30 seconds or so. Its been doing this for about a week now. The only way that I can restart it is to turn off the car. Any suggestions? Thanks

 

I forgot to mention my car is a 2005 RL

 

I would try a new NAV disc first. If that still doesn't work, I would suspect a faulty drive unit.
