There must be some reason why they did it this way... I suppose one
could purchase a USB adaptor cable...

No, but if you're worried about yours being affected, my suggestion
would be to fire it up on your car dash in the mid-afternoon sun, and
let it run for about an hour. If you receive weather for a couple
cycles and then it stops updating after a while, your unit is likely
affected.

I had an unrelated issue back in October and, at that time, Garmin told
me that they had made some minor modifications to the design of the
GXM30 since the initial production run. I suppose they could have
continued to make minor modifications since that time, so it's entirely
possible that those units affected by heat-related issue are rather
limited in the market. The Garmin rep with whom I spoke last week
seemed to feel that the heat-related failure wasn't widespread.

I still see the larger potential problem with the GXM30 as the
right-angle USB plug. It just seems that the plug is eventually going
to either break off, or break something in the GPS unit itself. It's
under stress after it's plugged in, and it's placed under even more
stress when you disconnect it, even if you're careful.
