vista screen flickers in GPS technology and devices Posted September 20, 2009 I did all the updates and a hard reset, and it seemed to help a couple of bugs I had. I notice though that the backlight screen flickers pretty regular, of course it's more noticeable when it's brighter. But it's not as bright as my venture hc. I am wondering if it's worth the trouble of calling garmin. If it means there is a loose wire, then of course it should be fixed, but if its never going to get worse, then it doesn't really bother me. If that makes any sense. Does anyone tolerate a slightly flickering vista?
