Can I take the the power for a dashcam from the center dome light thing on he roof? I don't fancy taking the wire all around the windscreen to the fuse box. [/list]

Here is a write up of what I did. Have fun
https://dashcamtalk.com/forum/threads/hard...ort.13011/

Not sure about the Aux but there is a Permanent Live up there in the Grey Plug to the left, red wire pin 1 if I remember right, plug normally used for sunroof.

Good write up. I'll give it a go on the weekend. Thanks.

Don't forget to buy a voltage regulator (if that's what they're called?) with the appropriate USB connector (either micro or mini) for your dash cam.

Most Dash cams need between 3-5 volts so usually you can't just connect it to 12 volt supply or it will fry your dash cam.

I tapped into one of the wires in the centre dome light (can't remember which one) and there's plenty of space up there for the voltage regulator box (you can get them on Flea Bay for about £10-£15).

Hope that helps. 2016 RRS SVR Estoril Blue

If we all point our RR's in the same direction and accelerate at the same time can we turn back time?

Would that not depend on the make of Dashcam being fitted, never had to fit voltage regulator on a Blackvue or Thinkware as they must be integral part of camera.

Probably most decent dashcams are 12v these days, my Thinkware is and so is the wifes Nextbase.
If you have the park collision recording on your dashcam you will need a permanent live as well as a switched one. That being the case, get a couple of piggy back fuses and drop the wires into the fuse box below the glovebox.

I piggy backed off Fuses 48 (Live) and 52 (Aux) fed the wires from the cam between the roof panel and headlining, down the door post under the door seal in to the fuse box, easy enough. If you have the rear cam as well did basically the same with that, fed the cable over the headlining and through the rubber conduit sleeve by the tailgate to the rear screen.

I used the ignition switched live up in the overhead console but instead of powering the camera directly I used a cigar lighter socket that I then plugged the normal dashcam power lead into... there's plenty of room in the headlining to lose the socket and it will make upgrading the camera much easier in the future.

How much do these reduce your insurance by?

Didn't know they did, will be mentioning it on my next policy L494 3.0L SDV6 Autobiography in Chile Red (Current)
L320 3.0L SDV6 Autobiography in Baltic Blue (RIP 29/03/2021 insurance total loss)

I don't know. I assume that was why Admiral kept asking me.

I agree with Scrumpy, most are between 3-5 volts. Check the dashcam instructions to verify what you need first. I would be wary of telling your insurance company, as if they give you a reduction on the policy, they will be expecting it to be on all the time your using the car. Nice get out for them if for any reason its not on or heaven forbid you are "slightly" above the speed limit when you have an accident. They are good to have if its not your fault, but you decide when to show the footage, not the insurance company.

As Col says, I'm sure there are plenty of 12v models out there and probably the more expensive ones have something built in.
It was more a word of caution so you check first and don't risk frying the Dash Cam if it's not 12v like mine. 2016 RRS SVR Estoril Blue

Have to admit I generally have the voice recording and speed stamp turned off
