Plans
Radio equipment
Mount the radio console and run power
Mount antennas and run to console
Car PC
I have an IBM ThinkPad? T23 that I no longer use. It would be useful for a Car PC.
Music
Would need to integrate with the existing head unit - CD changer or OnStar? interface?
There is mention of a serial data network, what can we do with that?
Can the OnStar? interface (buttons, microphone) be used for anything else? Hands free phone?
