Another +1 here, I also used this!

Does the Red with black stripe and Brown still apply for 2022 models? I have the drivers assist also.

Yes it does! But, the mirror tap now has a red and black (at least for my Cobra detector). Red goes to red obviously and black (on the mirror Tal) goes to brown (ground).

All credit due to AGS, I wouldn't be able to tell you this if not for his write up.

Thanks AGS and +1

the main piece was a PITA to get off, broke some of the clips, but didn't seem to have any effect putting it back on.

Another +1 here, looks so much better

So I did this method according to AGS as well. What’s weird is, the radar detector powered up once when I plugged into the wires that AGS described but as soon as I put the covers back on, the radar detector would not power on.

I then tried multiple more times to get it to work and even used different and new mirror tap wires with no luck.

I finally resorted to plugging into the smaller wire clip in the mirror that has purple plastic clip instead of the larger black clip. I plugged the ground into the far left wire and the power into the far right wire. After doing this, the RD powered right up.

I have noticed that the RD doesn’t appear to power down after the 5-7 minutes. I have no idea what wires I have actually tapped in to. I also have no idea why the other location for the wire tap worked the one time but then stopped.

I have an Escort Max360 so I resorted to using the auto power down function on the RD set at 1 hour which is the shortest amount of time. I have a 2021 M5.

I have installed and uninstalled this several times. Perhaps this may help.

"…as soon as I put the covers back on, the radar detector would not power on."

This usually happens when the leads are not seated right or deep enough alongside the wires that already go into the female end of the harness, and putting the cover back on pulls them out. I find the leads seat best when inserted into the right of the existing wires.



"I finally resorted to plugging into the smaller wire clip in the mirror that has purple plastic clip instead of the larger black clip. I plugged the ground into the far left wire and the power into the far right wire. After doing this, the RD powered right up."

That's because you got them seated deeper in that configuration.



"I have noticed that the RD doesn't appear to power down after the 5-7 minutes."

You plugged into somewhere that does not shut off like the ones indicated in the ISTA photo. With a long enough time sitting, this will trigger a "battery management" warning in iDrive, and possibly eventually lead to a dead battery obviously.


Hope this helps! You can try putting them in at a slight angle and they should slide in smoother, then straighten them out so they retain contact when the largest housing piece is put back on.

I appreciate the response. What’s most odd is that I have subsequently tried to install the wire tap into the indicated wire locations several times since then but the RD still will not power on. I am beginning to wonder if I somehow blew a fuse to those wires but I receive no error messages. Everything on the mirror appears to function.

If anyone has any other ideas as to why the RD simply will not power on with the wires in that location, I am all ears. I have now tried several different wire tap wires. It seems also like it isn’t getting the ground.

No problem!

"…the radar detector powered up once when I plugged into the wires that AGS described but as soon as I put the covers back on, the radar detector would not power on."

So it works as indicated initially? Then loses power once you out the cover back on? (This is what I gathered from your first post).



"…but the RD still will not power on."

Or you're not getting power at all, even when seating the leads as indicated? (This is what I gathered from your second post).



If it's the latter, check out my thread here:

No Power From Mirror Tap https://f90.bimmerpost.com/forums/sh....php?t=1940478

I include the dealer notes that resolved my issue at the very end. Do you have a voltmeter to test the locations indicated in OP's ISTA photo?

[mhjeep]

I may not have been clear. It worked the first time I plug it in only to stop once I put the plastic cover back on.

Now every subsequent attempt to get it to power on does not work when I plug it into those pins. This is despite multiple more attempts.

Thanks for the clarification! The dealer notes may help you then!

Did anyone manage to safely remove the big plastic piece in LCI models? The piece looks difference from the YouTube video and the picture the OP shared in my 23 M5C. I applied a lot of force and it won’t budge. Don’t want to break it.

I used this same procedure in my 2022 LCI M5 as when I put this thread together originally for my 2019. I can't image they changed it from '22 to '23. That large upper piece is definitely tight, it doesn't just slide out.

Does your plastic piece look like mine with 5 grooves on the sides instead of 4 in OP’s picture in the first post?

Sorry, I'm in Pittsburgh on business ... and the car is not! Maybe someone else that has access to their car now can respond.

Also, just an FYI, I am the OP.

Pre-LCI has 4 grooves.
LCI has 5 grooves.

Correct, but the question is whether the same procedure applies to remove the big plastic part. I applied a lot of pressure on the spot identified in the pre-LCI picture and pulled / pushed in multiple directions but the part is not coming out.

You are not the first owner to report that it is much more difficult to remove on the LCI. I have had both pre-LCI and LCI, and the LCI is much harder to remove by everyone’s anecdotal reports, but it will come out. Push with concentrated force by just using a smaller part of your fingertip to press down, and then push slowly towards the windshield for a second, then upwards.

So sorry, that was a really stupid comment. I inadvertently missed the earlier quoted posts so I thought you were just asking if there was a difference. Missed the context entirely. My bad!

No worries at all, and thanks for all the help. I will try again later tonight or tomorrow

You’re welcome! Keep us posted.

Can confirm LCI was a pain in the arse. I had to stop twice out of frustration and come back to try again. Eventually found the right spot and got it to come loose.
