Hi Up, Just a thought here. I'm assuming that once you remove your sunglasses the display is bright enough to be seen. You don't go under a "hood" or to a shade place to see the display. That gives me a clue.
Maybe you have
POLARIZED lenses in your sunglasses. If you do, your problem is not a dim Garmin display but light cancellation due to polarization. The Garmin and many other displays are Liquid Crystal Displays (LCDs). All LCD light is polarized which, in the right orientation, can be blocked by polarized lenses. Polarized sunglasses usually block horizontally polarized light.
A test for this is to rotate either your sunglasses or the LCD through at least 90 degrees while you observe the LCD through the glasses. If the "brightness" or ability to read the display changes considerably during the rotation you know that it is an issue of polarization rather than the brightness of the display.
This holds true for all polarized sunglasses and any LCD display - and LCDs are everywhere. Again, it's just a thought about your Garmin - it may be that the display is not bright enough for sunny places - that happens too.
