How do you exactly use the JCV file with the 3790T? I extracted the Philippines.JCV file from the .exe file downloaded from the official Garmin link and transferred it to the System\JCV folder of my 3790T but it seems to not work properly. When in route mode, my GPS turns into half-screen view (division is in the center of the screen vertically) but just shows a small square gray box in the center. I'm assuming this area is for the JCV function.
Also, is JCV not supposed to be on full screen with the 3790T? Do I get to use the Photoreal JCV function for this device?
What am I missing here? Please help me. Thanks.
