The problem for me is finding paper maps.

I've been using an old fashioned (ca 10 years old) GPS unit. Its maps are pretty out of date, but that rarely matters since paper maps and Google maps are also full of errors. Given how my phone is so much smarter than my old Mio GPS receiver, I don't understand why I can't get the Android equivalent to the software that's on the GPS; but it doesn't seem to be an option.
