I just ordered an asus eee tab transformer for my car, as car entertainment system and navigation system. I am planing to invest some time o modify the hardware of the car to fit the tab optimately in.
One thing I'd like to do is to let the car command the tab for boot and shutdown. I am thinking of using the asus docking station interface of the tab but I have no pinout of this connector at the moment. Can anybody help here?
Maybe it is also possible to throw typical "next", "back", "play", "stop", ... commands? I am expecting an serial interface or something similar. Since I am an routined embedded developer, with a pinout this should be no problem.
The second thing is maybe a software thing.
I have an bluetooth car radio which supports one connection at the same time. The Idea was to use the Tab with bluetooth a2dp but with this connection all calls on my bluetooth phone are ignored. Is there something to establish a android to android bluetooth connection where the tap plays the roll of a bluetooth a2dp headset.
So for music and navigation:
Tab <-> CarRadio
For phone calls:
Phone <-> Tab <-> CarRadio
The other thing is, can the android tablet keep 2 bluetooth connections at the same time from the hardware point of view?
Ok, I think I wrote enough for now ^^
Hope somebody can help with any information.
