Hi all, new user here, with a 2019 GLC 200 (type 204X). Looking at hardwiring my Nextbase camera to a permanent live fuse to enable parking mode.

I've looked at various threads with many owners frustrated with all fuses in the front being live/hot fuses instead of switched, but I can't find a proper source for a fuse that is properly permanent live - As I've read in various places, most of the "live" fuses go dead after 55 to 60 mins, so they might seem live at first, but after some time they stop providing power and the dashcam obviously powers down.

So far I've tried fuses 312, 315 and 316 and they all seem to go dead some time after locking the car - does anyone have a hardwired dashcam to permanent power, using the passenger side fuse box? Picture of my fuse box below, with fuse tap inside fuse 316.

I might have to ask a more generic question - for any of you who have hardwired their dashcam to a permanent live fuse, which fuse did you use?

If you know how to use a multimeter voltage, just check all fuses to see if the 12 volt maintained at off mode or accessory mode.

I do, it's just that I'm doing a Digital Nomad thing this year and don't have all my stuff with me that I've left back home - it would seem like a waste to buy a multimeter just for a single-time use 😅
I was hoping to get a reply from some forum members here to avoid having to do the above - I might just try trial and error different fuses and see how that goes...

This fuse info sheet is located at the trunk fuse box. Of 2017 Glc300

My dashcam was connected to an accessory power, fuse 216, not permanent.

Right front foot wall box is 301-341 fuse box.

I'm not sure but try this, might be permanent 12volt.
