Turn on Co-Driver Calls and Odo’s navigation announces the bends on your route a few seconds before you reach them: easy, medium or hard, left or right.

## Why it matters

On an unfamiliar country road, the hardest part is not knowing how tight the next bend is. A call a few seconds ahead gives you time to ease off before the bend, not in it.

## Calls like a co-driver

Bends on your route are graded by how tight they are and called before you reach them.

- Easy, medium or hard, left or right
- Bends close together are linked, for example “easy left, into medium right”
- Gentle curves are ignored
- Turns and roundabouts keep their normal directions

## Timed to your speed

Choose how early calls come in Call Timing.

- Early, Normal or Late: about 8, 5 or 3 seconds ahead
- Only at 30 km/h (about 20 mph) or faster

## Turn it on

Co-Driver Calls are off by default and need voice guidance.

- Settings → Driving → Navigation → Co-Driver
- Or from the Options menu during guidance
- Calls are spoken in English

## Questions and answers

### Does Odo warn about sharp bends?

Yes, during navigation with Co-Driver Calls turned on. Bends on your route are called a few seconds ahead as easy, medium or hard, left or right.

### Does it work without navigation?

No. Odo needs your route to know which bends are coming, so calls work during turn-by-turn navigation.

### Which languages are the calls in?

The bend calls are spoken in English, even when the rest of Odo is set to another language.

### Does Odo have turn-by-turn navigation on CarPlay?

Yes. Odo's navigation runs on the CarPlay map. You can say a destination, pick a saved, frequent or recent place, or choose from suggestions based on your past drives. Before you go, you can compare route options with their travel times. During guidance you get lane guidance, spoken directions you can switch off, a list of upcoming turns, and prompts to reroute or take a faster route. You can add a stop for fuel, EV charging or food, skip stops, or let Odo optimize their order. On the CarPlay Dashboard the map follows your car, and on cars that support it the instrument cluster shows a heading-up map with your route. Navigation needs a data connection to plan routes.
