TomTom and Renault unveiled an in-dash navigation system specifically designed for electric vehicles.

The Carminat TomTom Z.E. LIVE will be fitted on Renault's Fluence Z.E electric vehicle.

The two companies, which showed the system at the Frankfurt auto show (IAA) this week, said the navigation system receives battery information that lets it display the available range of the Fluence. The system also includes an eco-routing option, which lets a driver select the most energy efficient route.

In addition, the TomTom system will provide information about the availability of charging stations.

Giles Shrimpton, managing director of TomTom Automotive, noted that this is the first electric-vehicle navigation system the company is providing.

And Renault marketing director Stephen Norman said in a press release: "The electric vehicle program is of great importance to us at Renault and the Carminat TomTom Z.E. LIVE plays a significant role in its success.”

Renault was among the first companies to offer an embedded TomTom navigation system in its cars. Those systems are available to car buyers at a much lower price than traditional embedded navigation systems.

The Renault move, which was followed by other carmakers, is driving a trend toward more navigation systems in lower car segments. Previously, expensive navigation systems mostly featured in premium vehicles.
