My 2009 Mito has been experiencing navigation and radio problems lately. The radio signal got really weak and could only pick up some stations if I was close to where they were broadcasted from. I can still listen to the cd player though. Now my navigation has started to not work, and gives me a notice that I can not get a satellite signal. I have changed the antenna, but it did not solve the problem. Does anyone else know what else I could try next? Thank you for your assistance.
