But now to the power supply, cables enough to the cable from the rear view mirror of the heavens at the to move over to the glove compartment A-pillar, there the power pack itself (the small, really very small black box) is then there you have then almost again exactly as much cable to connect it to the ignition wire. I've just connected to the radio on the ignition plus and ground.
Otherwise, you can still say that the mini-USB connector 90 ° angled and so in my iTracker mini0801 by the instrument directly towards the sky shows and so no loop from the cord hanging there :)
So highly recommended!
