I'm getting a 1990 Mercedes 190, and I was thinking of having a plug and play macbook duo core in the boot of the car. It then will be connected to a touchscreen on the dash. Any tips, comments or thoughts on the setup would be much appreciated.
Yes, bookenddocks are the only guys around that make docks for macbooks and macbook pros. Expect to cough up around $300+. It replicates all ports on the macbook's, and still requires you to use your magnetic power connector.
