I just went out to my car to take a closer look. I see now that the words "GPS" are stamped on the case. So to have the GPS letters facing 'upright", I need to have the cable coming in from the bottom (not the side as shown in the picture above).
My cable is not long enough to get to the lower right corner (like in your picture).
If it works okay in the upper right corner, that's where I plan to install it. But I would rather have the cable coming in from top (cleaner look) so I may need to "flip it". I'll know more tomorrow when I road test.
Thanks.
