Right now if you own a SL class from Mercedes-Benz you can access data, make calls and play music on your phone directly through the mbrace system. However, if you have a C class or a GLK series car that option is not available to you.
Mercedes-Benz is currently developing a concept that will allow customers with C class or GLK series owners to be able to integrate their smartphones or iPod Touches directly into their car. Once the device is plugged in the car will take over the info and become the infotainment system. You can then control the smartphone directly from the car, allowing for hands-free calling and access to supported applications on the smartphone through the car interface. All updates will be done through the smartphone so you will always be up to date.
The system they are now developing for the C class and GLK series will allow those customers to get connected at a more reasonable price. They hope to have the system available for C class and GLK series cars by the 3rd quarter of 2013.
