Seriously. Much much worse.

First you had to pay a fortune for a device, with which you may or may not get very limited map updates. Then after that you had to pay quite a bit to update. Even then it could take a year for permanent road changes to make it to the map updates, and temporary changes were never shown. Road construction, wrecks, and temporary closures were your problem. And God forbid your route took you through a closed area because there was no way to route around it. You had to find a place to park so you could look over the tiny little map to figure out your own way around the blockage, or else you could pick a direction and then yolo your route until you were far enough away from the problem area that the gps would finally choose a route that didn’t go through the problem area.
And that’s just the tip of the iceberg. For instance, all the above assumes that it accepted the address you were going to as a valid address. There was nothing like the joy of typing in an address and having the device tell you that it doesn’t exist.
