I have EU version of Avic F-900 which has strange problem, that sometimes it doesn't start properly: when audio starts during bootup there's random interferences in speakers,v like AVIC were taking interference from some other electric device and touch screen is completely unresponsible, only harware buttons work. After I power off avic and power it back, unit starts up properly. I'm currently using V3 software with IDT Mod, these problems have been present with unmodded V3 too, unfortunately I dont remember if they were present with V2. Has anyone else this problem?
