If it's no Scottish it's CRAP!
Others have told me it doesn't suck juice after the ign is shut down???.
I see - so you'd rather believe others?
As I explained to you previously there is CONSTANT power to the diagnostic connector.
Some devices (like my VGate Bluetooth OBDII) have auto power shut-off - I do not believe the AutoRoute has this.
Try Google - lots of stories of cars parked at airports (etc) with drivers returning to find dead battery after a week - and that is with a CAR battery!
