The trial involved a fleet of Opel cars in Germany equipped with the ACUNIA OTF system, which enables users to subscribe and unsubscribe to an 'unlimited' range of information and services.
A number of service providers were asked to take part on the study by providing services that were compatible with the technology.
'We are very optimistic about the future potential of the technologies and services we are testing in this study. GM Europe's OnStar group, working closely with Opel, is testing what we think represents the future standard for in-car telematics,' said Jonathan Browning, vice-president of GM Europe's sales, marketing and aftersales.
'What makes this study particularly important is the participation of several innovative, industry leaders without whose support and expertise we could not have moved so quickly to test tomorrow's telematics possibilities.'
OnStar is GM Europe's information, communications and entertainment arm.
