The Garmin nüvi 2589LMT allows you to select an option labeled "Change Route" which will give you several options to change the route such as "Detour", "Detour by Distance", and "Detour by Road". The device will also allow you to preset the navigation settings to avoid different types of roads such as carpool lanes, and toll roads. Regarding street names and towns, the device will display the name of the street being driven on, however it will not show the name of the town being driven in on the map. However if the map is zoom out enough the name of the town/city will be visible on the map. {CW}
