This short road trip was the first with our new phones. They can be set up to act as a hot spot. Our favorite navigation software (CopilotGPS) runs on our iPad which we mount on the area over the radio control panel. It works quite nicely. As with anything new, there are some teething issues. Setting up one of our phones as a hot spot worked very well. We could get real time traffic which was fairly accurate. We could also get real time weather radar which was interesting to watch some big storms as they moved across our path. The radar app also superimposes our position which is handy. The most important lesson is that you really have to pull over to safely set things up or troubleshoot problems. We did that on a couple occasions.
The major disappointment was that CopilotGPS seemed to lose a lock on the GPS signal (a Dual XGPS150 gadget). Our iPad is WiFi only so it needs a source of GPS data. That is a little frustrating. Today's photo is a screen grab of the GPS software at work. The bar on the right shows traffic conditions out 100 miles. Pretty cool, when it is working.
Use of a GPS app will drain a smartphone's battery quickly. When hiking or triking (and using a GPS app like Map My Ride) I carry a phone-charging device. Not an issue in a car.
