Well it only took me a month to figure this out
When looking at the GPS page and you want to zoom in or out I have been using the knob
And noticed that every time you turn the knob the page would go blank and it would take about 5 seconds for the chart, track and waypoints to render again – was starting to annoy me a lot
I don’t know why but yesterday it dawned on me to try the + Plus or – Minus buttons and low and behold the screen zoomed without the screen going blank the view was instantaneously changed with no delay at all
WTH?
I mean it’s great I figured this out and now can zoom without a delay but why does the knob cause the screen to go blank?
