O2 XDA II Car Kit

Finally my XDA II Car Kit is complete!  I used the same charger circuit as my boat anchor charger, but redesigned it to include circuitry to obtain the audio left and right channels from the 22-pin connector.

The main charger box contains a circuit board with the TO-3 regulator, heat-sink, 8p8c socket (System cable) and stereo 3.5mm socket (Connects to Jaycar FM Transmitter to connect XDA II audio to the car stereo).

Below are pictures of the PCB, Kit components and XDA II in the cradle.  When I get time, I will do up a circuit diagram, plan for the cradle and cable diagram...
