I have been having problem with the head unit, specifically the Navigation system. I went to the dealership and they checked the head unit, and cannot update the software. They decided to replace the head unit. The head unit just replaced. After a short drive, I noticed my phone is not connecting to the head unit and charging via USB. I tried both USB port with no luck. As I was driving down from Seattle to Portland the Navigation frozen again even turn on and off the car few times with no luck. I called Cater Subaru where I have my car service and wait for an reply. I was later told by the service person that there is "blind spot" for the navigation system along Interstate 5 that the satellite will cause it freeze. Has anyone in the Washington/Oregon happen to you? What kind of action I can do other than Best Buy and get a suction mount for my phone so I can use it as Navigation in the meantime.
