Precondition with a Supercharger?

Got my adapter. On the next trip I might want to use a supercharger as my destination. The weather is very cold right now, so the battery might not get to 21C by just driving it.
The navigation will probably not recognize the supercharger as a charger, or won't even show the supercharger at all.
Short of selecting a different DC charger to fool the nav, is the only other way to wait for a map update from Hyundai?
