Radar Detector Hard Wire Installation?

[justjim95]

For those who have a Uniden R7 radar detector, the correct Blendmount or one that works is the BR7-2014. Just tell em it's for a 2020 BMW M3. Still battling with the damm plug....it is so tight back there. LucidJazz thanks for the tip with the cap and that hasn't helped yet. Also based on the location of the radar detector it works fine there too. I heard early on some detectors didn't work except the Unidens.

Do you have free range moving the mirror? I tried to use one of my old Blendmounts. It worked as long as I didn't want to adjust the mirror (let my wife drive).

Actually, I can move the rear view freely as I was surprised myself

I have a Dream on order and I’m curious if anyone has found a way to hard wire a radar detector? In my last car (Porsche Panamera) I had it hardwired from the fuse box (under dash) and then up the A Pillar and inside the headliner. Obviously this won’t work on the Dream but maybe there is a way to connect through the back of the rear view mirror?? I know this was possible on a number of other cars but don’t know about the Dream? Any thoughts?

There is a battery below the 12v cigarette lighter socket on the right in the trunk. That is the best place to wire it from.

Tapping into the mirror with a mirror tap is the cleanest it's just a pita

I specifically stayed away because the Lucid techs specifically told me not to mess with the mirror and electronics there, so they told me not to mirror tap

At the rate I am going if I can't tap the mirror I may have to go to the trunk. Although those who were successful in tapping the mirror don't seen to have any issues.

I'm just telling you what the technicians told me. The cameras are there behind the mirror as well as the dimming system and various other computers and sensors

Definitely a frustrating process. I do have a spray paint can top that’s jammed in between. I’m trying to hold the white connector with one hand while trying to insert these pins with the right hand. I’m having a hard time jamming the pins alongside the existing red and black wires. Did anybody disconnect the green connector in the back of the white connector to try to get more mobility and attaching these wires? Any tricks in

jamming these wires alongside. I’m trying to use a plier to hold onto the white piece and then use my right hand to jam the wire in alongside of it but I’m having difficulty in doing it.

Was able to get it to plug in but couldn’t put together the housing back together to lock into place. And in fiddling around with it the wire tap got dislodged. Going to abandon the wire tap route. Now have to figure out how to get the housing back together without making a service appointment. Getting some resistance in pushing the middle back up. I did seat the white connecter back in that seat as shown in the pictures here.
