    Hi,

    When i turn off the ignition in my car, the 12 volt socket can still be used. Can this be changed so that it powers down? I want to keep my Sat nav pluged in. On that question if i unplug it and leave the power adapter in will it drain the battery?

    Cheers

    You would have to rewire the socket to a 'switched +ve so that it was only live when thee ignition is on.

    Not exactly sure about the second question. These power adaptors are often voltage/convertor/regulators so they may still use power when plugged in.
    Should be easy to find out from the manufacturer

    It shouldn't drain that much power from the adaptor lead, you should be fine.

    I wouldn't leave the Sat Nav in the car as it will probably get nicked

    I've had mine plugged in for a 3 weeks when my car was parked up in my garage without a problem. The draw on charging is mA so shouldn't really concern yourself too much. Besides, the charging circuit probably cuts off when unit is charged.
