My issue isn't so much the pain of entry — although it is a pain — as the fact that Google Maps provides better directions, taking into account current traffic conditions, than my car's system. OTOH, my car's system knows about highway amenities like food & gas, and has a neat feature where it displays a preview of what certain turns look like. I would love to integrate them somehow.
