You know over the last few years I have become more and more dependent on my GPS when driving a distance-I was wondering does anyone make a GPS for 6-volt cars?

I would suggest spending about $20 and get a 6 to 12volt converter. Then you can use the 12 volt adapter for both your GPS and phone.

An alternative is to fit a USB port in your car. You can get them now to run off 6V. They are also very cheap to buy. Presumably Chinese!

I use my smartphone maps to navigate in 6V cars, but only when I'm really lost because of limited battery life. I have a USB port in my 12V Clipper, which solves the problem nicely. My Garmin GPS will run off the cigar lighter.

I bought a 20,000 mAh battery with 4 USB ports. It will charge your phone and tablet several times before depleted. I think I can charge my phone 10 times before it needs to be charged. It's the size of a phone but about half an inch thick. I use it when traveling but also between my different Packards.

I certainly agree with BDC about the portable battery solution of powering modern electric devices. My wife and I both have 26.8K, 3 USB port, portable batteries and use them continuously. Later my wife thought the battery weight was a bit much and we bought a 10K unit (less weight and less capacity). She can roam all day without running out of power to recharge.

As a test, I plugged-in my Garmin into one of the larger portable battery and everything worked just like it was plugged into a 12V 'cigarette lighter' socket. I did run into one 'glitch'. The Garmin came with a power cable that had a small format USB connector at the GPS end, and a 'cigarette lighter' plug at the other. I used a cable from a Canon camera that had the same small format USB plug at the camera end, and the large rectangular USB connector that the battery has.

If you decide to go with the portable battery solution you will also have a pretty handy way to power your GPS, plus the ability of recharge phones (etc.) on the go. You may have to find a cable to make the GPS work, but the cable you'll need is pretty much standard.
