NAV SYSTEM SCREEN

2000 BMW 740

Electrical problem
2000 BMW 740 V8 Two Wheel Drive Automatic 140000 miles

My nav system screen turns on and off intermittently. Didn't notice it when we bought car in december and does not occur in the morning hours. Problem is constant in the afternoon and evening. Could the cpu be overheating in the trunk and would a computer fan help?
