Well, I'm having problems with a multimedia pioneer avic f 900 bt in this video you can see my problem. The strange thing is that if I leave it off for a week for example, when I try to call him again, it will work normally, but for a few hours and then stop working again and get caught, as in the video! Please, I need your help because I'm Brazilian and here there is the pioneer technicians who solve this problem!
