Have a 2016 i30. It has two 12v in front and a 12v in boot.
Looking at dashcams and A119 seems good value. More expensive then some but better quality.
Do they just plug into cigarette lighter?
How long is the cable? With the boot, plug is obviously fixed but boot opens so need enough slack for it to work.
Is there a clean way to install in the front? Ideally don't want a cable running across the whole front dash and up the windscreen.
I have the a118c and im guessing they arent that much different…
Yep straight in the cigarette lighter port.
The cable included with the a118c was quite long, long enough to go from the cigarette lighter in the centre then through the glovebox, up the pillar then to the centre of the windscreen.
And to install in the front you should go through the pillar then hide the cable in the roof (though your car might have airbags in the pillar? which might make it annoying)
