    Have you modified or can you answer me this:

    I want to modify the voltage output of the LCH-6 Car plug to 3v.

    The trim pot on the inside does nothing I can see on the meter, so
    I'm guessing it maybe a resistor control. Without the schem its hard
    to know for sure.

    I have this unit in my surplus but I no longer have the phone, so
    I thought I would put it to better use on my GPS.

    Thanks for any assistance.
