Dash Cam for 2025 HS PHEV?

[Eponemuss]

Morning all!
Does anyone have experience of fitting a dash cam to a new shape HS PHEV? If so, what type and was it straightforward? Any issues with power drain, or similar, afterwards? I'd like a neat one. No cables trailing through the cabin.

I managed to hard wire mine and hid all the cables in the roof lining. The Fuse Box on the Drivers Side is a little easier to access in the new model as the little drawer just pops out and exposes the fuses. The fuses are 3 prong fuses. I can't remember which fuse I chose - but it was 5A and used a piggy back fuse (which is why you need to know it's a 3 prong fuse). This does mean that it is only active when the ignition is on.

Other people have used ODBII adapters which give a USB output, so it just gets plugged in just by your left knee. This does have permanent power - so you need to have a dash cam that shuts down after an appropriate amount of time or is good on power usage. I don't have experience of these.

Hiding the wiring in the roof lining is very very easy. The only problem that I have is placement of the camera. It's currently on the passenger side as high and as close to the middle as I can get - but with the suction cup holder etc. it's still quite low down and obstructs the passenger side view.

So you might want to look at a slimline style camera that uses a sticky pad to stick to the windscreen instead of a suction cup, to get it out of the passengers eye line.

The 2-pin micro adapter also fits into the 3-pin fuse slot. I didn't pay close attention, but I plugged the 2-pin micro adapter into an empty 3-pin slot for 12V continuous current. For ACC, I measured a 2-pin fuse with a measuring device and plugged the adapter in there.

I also have the A229 duo - what did you use to get the rear camera cable through the headlining. Did you experience any difficulties with this bit?

After two major rear end shunts (£6k insurance claim & £8k claim - both in previous cars) I fitted Nextbase 322 front and rear cams in my MG HS PHEV, took about an hour and no major problems hiding the wiring in the headlining / down door pillar trim. Didn’t hard wire, but can’t imagine it would be a problem with a fuse adapter.

How easy is it to remove the headlining and A pillar covers sufficiently without knackering the clips that holds them in place. Have you all installed the cables above the airbags? I've gone for the OBD II connector and a slimline camera from GKU. https://amzn.eu/d/iSqQOZv . I'm undecided whether to install the front facing camera high up to the left of the RVM and radar box, or whether to install it sitting at dashboard level to the front. Thoughts?

Can anybody who has installed a rear dash cam in a new hs phev please tell me how the rear high brake light surround is removed and if possible any pics of the final results.
TIA

Take a look here - I've added a picture showing where the connectors are - hope it helps......

UPDATE Using the trim tool that came with the dashcam kit - I inserted it at the top of the right side and moved it down the join and gave it a hard tug and it released. Did the same on the left side. This makes it easy to get the trim tool into the gap at the bottom and give it a hard tug around every 6 inches (there are about 6 clips holding the panel in place - and they are really tight). Be careful - the cable for the high brake light is connected from the body of the car to this trim). This was a test run for me and I will take a pic when I next have it removed (when I fit...

I picked up my new PHEV HS yesterday, I used to have the older PHEV with a Nextbase 622 camera connected via an OBD port adaptor cable. I just swapped this over in a few minutes, it’s real easy to just push the cable behind the headline and side trims down to the bottom of the dashboard, I unclipped what appears to be a filter tray and looped the spare cable in there and just plugged into the OBD port. Very simple to do

Do you pull the little drawer straight back to release it? Thanks.

I think I must be missing something, my HS has a USB socket on the left hand side of the central housing at the top middle of the windscreen. This is powered when the ignition is on.
Of course if you need front and back cameras and a permanent supply, this would not be suitable.
