After a couple tries, I finally found a power source that switches off (after around 6-10 minutes).

Disclaimer: I am not responsible for any damage you might cause to your vehicle.

Parts used:
RJ11 Mirror Wire Tap - I used the smaller tap inserts.
BlendMount BMX-2018 (for Escort Max 360)

Instructions:
Step 1 - Remove the plastic mirror housing. This can be done by using a plastic trim removal tool. I started from the top and slowly separated the trim.

Step 2 - Remove the bottom plug. This can be difficult to remove. I had to use the plastic trim removal tool to keep one side of the plug down while pulling on the other side. Be careful while removing it.

Step 3 - Insert the wire taps. The red tap (12v) inserts into the red/blue wire plug socket. The black (ground) inserts into the brown/black wire plug socket.

Step 4 - Reinstall the bottom plug and hide the wires. I ran the cable out by the mirror stem.

Step 5 - Reinstall the plastic mirror housing trim

Step 6 - Install BlendMount

After doing the same, now getting a “Battery Malfunction” check control message. The message stays even when I disconnect the wiring for the RD. Any ideas? I can’t get my Carly to work (either the car or ios13 issue) or would have the code detail as well.

Sorry, I have not had that issue.

Rear view mirror housing pics

Thanks tturbolife for post. Thought I'd return the favor and share pics of rear view mirror housing for others to see the clips that need to get undone and pulled apart.

The housing is 2 pieces with clips along the middle that need to be undone. I inserted a screw driver between the headliner and top right area of the housing. Pried gently outwards where after the first clip got undone then used my hands to undo and pull apart the remaining clips.

Wasn't very difficult and after taking off the right side housing, I pulled the left side housing off with my hands.

Also no need to pull out the wiring harness to put the mirror tap spades in. The rear view mirror itself just slides off. Push the mirror downwards and it will just slide off.

Will also confirm that power does auto shut off after 6 minutes.

Do have issue where laser alarm randomly goes off. Don’t have gesture control. May need to tape rear sensor or turn off laser altogether in V1 setup.

To previous post as to warning message after hard wiring - no I did not get.

Laser warning is pretty useless anyway. Mine always got set off by Infiniti SUVs

I can also confirm that this works and it shuts off, my mirror housing is huge as I have the assisted driving package but the clips are the same.

I also spliced into the same wire for my USB powered dash cam (because BMW still has not launched the drive recorder for my car). My dashcam is USB powered so I just soldered in a small DCDC converter on that line to go from 12v to 5v and soldered directly into the USB cable.. works perfectly.

Also confirmed with a multi meter that:
Red/Blue = +12v
Brown/Black = Ground

This is the DCDC I used: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Just bought the escort 360, blendmount, and RJ11 adapter. Going to try this in 2 weeks. Thanks for the write up!

I wonder if this is applicable to a dashcam setup as well.
What's the voltage output at that connector?
What's the accepted voltage for the radar device?

Thanks much for pulling this info together guys. Wanted to add another success to the thread. Just completed install in my M340.

Also wanted to highlight the suggestion to remove the mirror. This is 100% the way to go but watch out for sudden release or you might unnecessarily strain the wire harness you’re trying to use. Put two hands on the mirror base right up against the windshield and apply gentle, progressive force down the plane of the windshield. There is minimal slack to the wires so as soon as the mirror is free it’s pulling on them. Immediately bring one had around and disconnect.

Agree! I did the same thing. I tried messing with the wiring harness from behind the mirror for a few minutes, and then just slid the mirror off and that was much easier. I used one small pin for the red lead, and one large pin for the black ground lead. Worked like a charm and both were nice and secure. Thank you all for your help and the pictures!

I just did this earlier. Broke a number of those small clips keeping both the left and right pieces of the housing together. Luckily, it all went back together and is holding as if nothing happened.

It's a $25 part if you want to replace it[IMG][/IMG][IMG][/IMG]
