In a recent survey conducted by Inrix, 72 percent of respondents said that parking availability information is the feature they want the most. "Real-time parking is the most sought-after navigation feature because it addresses a pain point that affects everyone," said Inrix VP Joe Berry in a statement. The BMW sedans will also get Inrix's traffic service that gives real-time traffic flow, travel time and accident information.

When it comes to finding parking, there are a few apps that have tried to remedy the problem. Ford has an app that lets you find garage parking, MonkeyParking started out by letting people pay other drivers for public parking spots that they're getting ready to vacate but has since switched gears to private parking spots and one of the more well-known apps, ParkMe, was acquired by Inrix in 2015. Google Maps has also been working on a feature that will tell users how difficult parking is likely to be at their destination.

Inrix's On-Street Parking service is live with BMW in seven German cities as well as Boston, Chicago, Los Angeles, New York, Philadelphia, Phoenix, San Francisco, Seattle and Washington DC. The company says more cities will be added throughout the year.
