And even then, there is a massive difference in "resistant." My Rolex deepsea is water resistant to 12800 feet, but not waterproof. Iphone X is water resistant to 1 meter, not waterproof. So you are definitely correct, this marketing crap is very misleading to many.
OP, the IP ratings of electronics is what you are looking for...rigid lights for instance are IP67 or 68 rated, which means that even if submerged, they will still function. The electronics on a jeep dashboard are probably water "resistant" to the point of a solid wet sneeze, meaning, a little bit of a sprinkle they can tolerate. Actual rainfall, no way. I don't see any seals around any of the electronics, I don't think the circuit boards are dipped in silicone, etc...that was a big marketing mistake on their part saying that, because while IMHO, most people understand that you can't submerge the dash under water, MANY would assume that the only other possible water intrusion into the cabin would be rain, and they made it sound like it can handle that. While I personally never remove my hard top, my advice for those that do and travel topless, some company, I can't remember the name, maybe even besttop, make an emergency top specifically for cases like yours. Might be a wise idea to have one, just in case something like this happens again.
