As Paul Tomblin has mentioned, navaid.com will allow you to load aviation
waypoints. You cannot load an entire database. What you can do is load
aviation waypoints as user waypoints.
Now, when switching between aviation and car mode, I'll have to keep
reloading the GPS with aviation and auto data respectively, correct?

I don't think so. The points you load from my site will show up as user
waypoints, and won't touch the auto data. I don't know if you can
configure your GPS to only show user waypoints in one mode and not the
other - my GPS doesn't have modes and always shows user waypoints.
