2008 I had a totally offline map of all of North America in my car's aftermarket radio (7" touch screen, AM/FM, DVD player, GPS, analog TV, SD slot, all running a version of WindowsCE that was already outdatted). System cost me about $400. Bought it so I could do backroads road trips/exploring by car, as it didn't need (or even have) a way to connect to the 'net to do it. I can still get updated maps for it, but I don't bother.

Handheld gps's with offline maps go back even further. I was using them from '03 to '08. Garmin made a bunch of ones that were no bigger than a early-gen blackberry. Back then it was relatively easy to get pirated updated maps for them.
