My wife's car isn't that old (2017 model) but using the navigation is a painful experience. Inputting an address takes multiple minutes and can only be done by turning a knob one letter at a time. First, state. Then city. (There is no defaulting to current location, so this must be done every time). Then street name and finally numerical address. If any of these items aren't in the database, you get to go back and start over or try for the hopefully nearest address that is in the system. It's a mess but sometimes necessary.

It also no longer gets traffic updates since the modem is 3G with no upgrade path currently. It does not support AA or Carplay. I hate it but she loves the way it drives, so we'll be keeping it for a while.
