Hardwiring Radar Detector

Does anyone know where to tap into the mirror/sunroof control console area for a switched power source to hardwire a radar detector in the new 2017 E300s?

Did you ever get an answer to this? I just took delivery of my 2017 and wanted to install as well since there is no other power source for my Escort. What did you use as a mount? Thanks

Though I no longer use a radar detector because radar has been replaced by LIDAR, I used to connect to the power in the sun visor.

Where I'm at....

I am a bit fearful of taking the mirror housing apart ... but was able quite easily to run the Valentine 1 RJ-11 cable in the headliner, tucked in down the right of the windscreen & from there down to the passenger foolwell fuse box.

FYI I used a tap to run power off of a 5amp mini fuse & grounded to a threaded nut that's in the fuse box. However none of the mini fuses seem to be switched so i'm waiting for a ATO size tap I ordered to arrive - hopefully one of this is switched power. Will keep you posted.

I connected to the sun visor wire above the headliner near the hinge.
That may not be switched in the W213.

Have mounted Valentine V1 on sun visor of many MB's. Run power cord down the A pillar to either the fuse box or center console. My local shop does this in less than an hour. Not a big job.

Anyone know where to find the fuse box(es) schematics?
In particular the one in the boot/trunk.
I need to install 2x 20 fuses that switch off when car's off.
