gps. But tonight, a warning. A family on a road trip with their little girl and dog ended up stranded in the Oregon snow after a gps miscue. Here's Gloria Riviera. Reporter: This snow-packed road, stopping one family in their tracks. The next thing we know we were sliding and we got stuck. Reporter: The sanquists, mom, dad, their 9-year-old daughter and the family dog, all on the way to California from their home in Oregon. The gps mapping the shortest route. Just one problem. It took them up this unplowed mountain road. Snow socking them in. No shovel. No cell phone service. I am not even sure, if I had a shovel, I could have dug out. Reporter: The family huddling down until morning. With when Ron hiked two miles for help. Search and rescue getting them back on track, and issuing this warning for all drivers. Many gps and map systems can steer folks in the wrong direction during winter travel where conditions are poor. It was pretty scary, especially because to the left was a downgrade. Quite a steep one. Reporter: This is not the first case of a gps mishap. This driver followed her gps straight into Canada's frigid Ontario bay. She made a quick escape, but her car was a goner. Thankfully, the sanquist family had enough food and gas to last the night. What should have been a seven-hour trip took more than 24. Tom? Gloria, thank you.
