Hello, i have a Pioneer AVH-X5800DAB with AVIC-F160 nav. Problem is when i power on the system, i see, when i press the mode button, the sign ¨navgate loading navigation software". But the loading stops and black screen. Not all the time, sometimes, 1 on 5 or 6 or 7 times trying, the software is continouing loading and i see the navigation card, but after some time it stops working, black screen. A very less time i can use it. Hope someone can help. AVH has latest firmware, Avic has latest card of Europe.

Thanks, Pieter
