You can fuse tap most of the fuses, although most on the right are always on IIRC (276-280 etc). I use F252 and F271. I suggest you find an accessory fuse (from the fuse map), open the trunk, then let the car sleep (takes about 6 minutes, hazard button will turn off), then check the voltage on that fuse. There are OBD adapters that you can use as power supply as an alternative (just so you can hide the wires). I suggest using an external battery module to power your dashcam though, the electronics for this car seem quite sensitive.
