This is our navigational set up. We have two GPS devices. The one at the top is an old Garmin device. Ginny sets that for our ultimate destination of the day. The bottom one is an iPad using the CoPilot GPS app which works just fine for us. I program it every day for the route and all the stops along it, mainly gas stations. The Garmin is hard to use because you really have no control over the display to zoom out or in. It does give ETA, Distance and Time enroute. That is handy. The iPad has a totally adjustable zoom level and traffic display. That traffic display is very handy. We have avoided long delays on several occasions by navigating around the problem. I have tried WAZE and others but they just didn't have the style of interface that I like. It seemed to have way too much user input like social media type stuff. If I need a different look at the route I use Google maps which is quite good. Its only shortcoming is that you can't plan a multi stop route. So that is the story and I am sticking to it.
