Correct, garmin says:

What Garmin does not talk about is "driving rain".

I looked it up years ago and just tried to find a source but can't... Anyway, as far as I know 7 definitely does not cover water that is moving at highway speeds. I think even IPX8 (the highest IP level) does not guarantee protection against water moving at highway speeds.

Basically, you can ride in the rain but only if your device is behind some kind of windshield, unless the manufacturer specifically mentions what speed water it can handle (eg: a marine GPS might handle "driving rain" but boats are slower than motorcycles so I still wouldn't trust it).

That's nice of them to replace it.

I think you were probably also unlucky. 5 minutes is not very long and IPX7 *usually* can handle a bit of rain (actually, even non-waterproof devices can usually handle rain).

I wonder... did you try pulling the batteries out and letting it dry for a week or two? Pretty good chance it would work after that, as long as no salt water/etc got in. I'm guessing if you sent it back to Garmin they will have done that and used it for spare parts doing warranty repairs for other people.
