Hi All, Thanks in advance for any help you can offer.
I have a Thinkware Q800 pro, which I fitted and later removed from my old BMW. it worked perfectly there.
I have tried to install in my new car, 2019 mercedes cls350, but it has Keyless Entry, so circuits I would have previously used and assumed were dead while the vehicle was locked, are now constantly live.
I have found a good grounding point, and a good constant 12V in the passenger footwell fusebox, but all circuits there seem to be constantly live so I cannot find a switched 12v supply.
Does anyone have any experience of hard wiring in this vehicle, or advice on how to find a switched 12v without ripping the whole vehicle apart?
I'm considering a work around, by purchasing an external battery which looks to be wired just to constant 12v and then grounded, so overcoming the issue. But its a last resort as getting batteries shipped to Ireland is difficult and buying local generally involves the typical irish price multiplier, seeing me pay circa EURO400 for a $200 Battery.
