About Kermo: No-GPS Car Navigator
Coming up to an interchange when your navigator suddenly puts your car in another part of town and tells you to turn around? When GPS is gone or shows the wrong place, I help you keep going.
Kermo is a car navigator that works out where your car is on the route, even when GPS lets you down.
One app, two ways to use it: with an adapter and without one. No adapter? The no-adapter mode turns on by itself. Have an adapter? Plug it into your car and connect it to me, so I get the speed straight from the car.
WHY KERMO
• Speed from the car itself. With an OBD-II adapter I know how fast you are going, and the phone's sensors help me spot the turns.
• I help when GPS gets it wrong. I work out where the car is on the route, so you can find your way even when the signal is gone or shows the wrong place.
• No adapter? I'll still get you there. You mark moving off and stopping with the buttons, and I guide you along the route. I take the speed from the limits on the roads of the route.
• You can help me too. The screen shows whether GPS is there, gone or showing the wrong place. If needed, you can correct the car's place on the map.
HOW IT WORKS
1. Show where the car is: put the crosshair on that spot on the map.
2. Say where we're going: find an address or pick a place on the map.
3. Drive off. With an adapter I get the speed from the car and spot the turns with the phone's sensors. Without one, you mark moving off and stopping with the buttons, and I show your progress along the route.
WHAT THE ADAPTER IS
A small device that plugs into the car's OBD-II port, usually under the steering wheel. It gives me the car's speed, and the phone's sensors and the road map help me work out where the car is.
Look for a compatible OBD-II adapter (ELM327) with Bluetooth, Bluetooth LE or Wi-Fi.
EVERYTHING A DRIVER NEEDS
• Speed cameras: I warn you about them on the route.
• Routes to choose from: pick which way to go.
• Where you parked: I remember where you left the car.
• “Home” and “Work”: a route in one tap.
Download Kermo now, and the next time GPS is gone, you'll know where to go.
