Automotive USB…

I would like a USB hub in my car.

I would like it to be connected to a “control centre” with a nice touchy feely responsive point’n’click screen.

I would like to be able to plug my WMA/MP3 player into a USB port and have the music play through the car’s own sound system.

I would like to be able to plug my SatNav device into another USB port and have the control centre kick into action.

I would like to be able to connect my mobile telephone to the USB hub and be able to download celebrity voices for the aforementioned SatNav.

Where can I get such good stuff?

If it doesn’t already exist, somebody with the knowledge, please, get on the case; my fee is very reasonable.
