Should I “update” my Roadmate Magellan GPS

We used to use Garmin GPS systems but with the advent of cell phone apps such as Waze and new vehicles having built-in navs we no longer use them as the phone apps have real-time updating as do some of the on-board navs. If the GPS has not been updated in 5 years I would be concerned about road changes, etc., that might not be on there. That said I would update, hope for the best but be prepared to get a new one if that is your preferred method or update and use a phone app as a back up.
