Chris loves to drive, and I love to be a passenger. An RVing match made in heaven.
I call myself a “professional passenger,” because I try to be somewhat aware of our surroundings and the traffic around us even though I’m not driving, so that, for example, I don’t lean forward to pick something up off the floor just as Chris is needing to check the passenger side mirror because a vehicle is passing us on the inside lane.
But what makes being a passenger especially fun for me is being able to use technology while we’re on the road. With my iPhone and a few of my favorite apps, I’m able to help navigate our way to almost anything. (I’ll leave it to Chris to comment on how much – or how little – he likes sharing the navigator role with me.)
With the Google Maps app on the iPhone, I can just plug in our destination’s address and tell it to route us from our current location.

It gives me a list of turn by turn directions, just like a GPS, as well as letting me see details of the route plotted on a map.

What’s more, I can also use “street view” and, before we get to a destination, scope out whether a parking lot will be large enough to accommodate the motorhome, as well as how to get into and out of the lot.

(At any time I can tap a symbol on the screen that will immediately cause the app to find our current location anywhere where we are, so it’s not like I have to be watching the map all the time, either.)
Another free app that we’ve found to be very handy is something called Gas Buddy. When you’re filling an 80 gallon gas tank, you want to find the cheapest gas around whenever you need a fill-up. Gas Buddy automatically finds our location and gives us a neat list

(or map view, if I prefer) 
of all nearby gas stations and their most recently reported gas prices. (The gas prices are reported by users like me, who submit prices as we go.) This app came in especially handy on this trip when we were just about to cross the state line from Georgia into North Carolina, and we discovered that gas prices in North Carolina were about $.30 a gallon more than they were in Georgia! Made great sense to fill up before we crossed the state line. Thank you Gas Buddy!
When we get hungry, we like to use an app called Urban Spoon to find restaurants. As with the other apps, this one finds our location and tells us what restaurants are nearby. We can see ratings, read customer reviews, see what critics have had to say, look at the menu, map the route to the restaurant, and, when we’re all done eating, add our own rating, review, and pictures.

Sometimes when we’re traveling we like to listen to the radio. While “scan” happens to be my favorite radio station, it kind of drives Chris crazy. So another app that we use is called TuneIn Radio. It allows us to select whatever kind of music or talk we happen to be in the mood for. We can either listen directly from the iPhone (connected by a wire/jack to the cab stereo) if the station is not local, or, if it is local, we can tune the cab radio itself to that station.

But sometimes Chris may want to listen to music and I would like to listen to something spoken. I enjoy listening to podcasts, particularly of Catholic Answers Live (I think of it as “continuing education”). Other times I am more in the mood for “reading” a novel. That’s when the Overdrive Media Console comes in handy. With Overdrive, I am able to browse for and borrow audio books from our local library, and then I can listen to the books whenever I want.

What I like about listening to podcasts and audio books, as opposed to reading, is that I can be kind of simultaneously watching the scenery and listening.
Because Chris likes to plan a day or so ahead where we’re going to stay, we don’t use these next two apps all the time, however we do like knowing that they are available: one is called RVPark Finder and another is Woodall’s. They allow us to look for parks near where we are or near some destination down the road. They give us enough information about the campgrounds so that we could, in a pinch, select a campground right from those apps and not even need to refer to the Internet or paper directories.
I also have an app that will locate YMCAs in case I want to go swimming or Chris wants to work out. And another one called Catholic Mass Times that locates Catholic churches by current location or by destination, and provides Mass times, church websites, phone numbers, and so on.
As you can imagine, all this use of the iPhone would drain the battery down really fast. Well, one option we purchased when we bought the motorhome is a built-in inverter. So next to my “professional passenger office chair” is an outlet powered by the inverter. I can leave my phone, my computer, and our 3G wireless hotspot powered on all the time, and never drain down any of my batteries.
And to think when we first started RVing we used paper maps, paper RV directories, made telephone calls from our pre-paid TracFone, blindly selected restaurants, and were limited to listening only to whatever radio stations happened to be available where we were!
I’m always open to hearing about other travel apps, especially free ones, so if you know of any, feel free to leave a comment, below.
