Hi,
Just a quick question, as I am looking for some advice on how to hardwire my A118C to my 2005 (55) BMW E60.
What is the best, cleanest, easiest, safest way?
Thanks
Stu
I just bought some varient of the A118 for my Truck, but I happen to have an E60 M5 that might get a dash cam if this one works out. I've hardwired both my my vehicles for various things, particularly, my radar detectors, so there are typically electronics that are usable up in the headliner.
One thing I will advise, your vehicle runs about 12-15VDC right off the tap. The A118 is USB and therefore requires 5VDC. If you hardwire without a transformer, you will fry your A118, that's why you have that cigarette lighter adapter with a red light on it. Assuming you're mechanically inclined, there's a plastic panel up by the sunroof, it contains the sunroof controls, map lights, bluetooth mic, etc. That will pop out and expose all the wiring. I don't know which 2 wires, off hand, try an internet search, or test the leads. You'll want to mount a small USB (12V to 5V) adapter up in there.
