    Well it looks like my OBDII isn't the only thing draining my battery.... Now i'm not 100% sure but i'm thinking it might be the XM Module since that is the only thing that is getting an external power source without a control signal. It might get the control signal from the USB connection but i'm not 100% sure. Anyone have any ideas?

    When I was having current problems like that, I put an amp clamp on the + line of my battery, and started unplugging stuff one at a time until the current draw went away.

    I would expect the bluetooth to add even more current draw than wired. Probably around 100mA since most are about 60mA, plus the added 100mW class 1 and circuitry that's at least 90.

    Yea but i'm losing power even with no OBDII connected anymore. I'm wondering if I have a faulty capacitor. Can't imagine it being bad to the point where its not holding its charge and constantly trying to charge itself. I guess its possible...
