I know this thread is a bit old but I ended up installing the OEM wireless charger and wanted to report back. It works great 👍

View attachment 235526

Just a note for anyone who wants to order it - I have an iPhone 12 Pro Max and I have to take it out of its case for it to fit. But any phone smaller than that would have no problem at all. It's pretty awesome because now I can have wireless CarPlay and charge my phone at the same time. You can see I've velcro'ed the CarPlay adapter to the ceiling of the compartment.

You do kinda need to remove the glovebox to install it though. If you don't have the cooled AC glovebox, I recommend you order that too and you can do both these mods at the same time.

I used this thread as a guide: https://forums.ross-tech.com/index.php?threads/12055/. Though, I took some liberties with the wiring because I just wanted to get the center console back together again quickly. Instead of running the +12V wire, ground and BCM wire from the compartment over to the fuse box, I cut all of them much shorter and just spliced +12V and ground into the cigarette lighter wires. I did not even try to attach the one wire to the BCM - it works fine without it and my guess is it's for charging while the ignition is off, which I don't particularly need. Then the two final wires plug into the gray connector in the quad-lock of the infotainment in the glovebox.

I could have made it even easier on myself by ordering one of these (just the harness). Then there is no need to splice into the existing wires.

For coding, all you need to do is enable bit 0 and bit 5 in byte 15 of module 5F's long coding.

Definitely recommend it!
That's awesome!! I really like the wireless charging in my gf's Taos, and having wire wrapped around the shifter is sometimes annoying. Thanks so much for the write up! will look into that for sure!

Nice write-up.
I did this retrofit in my previous car and managed to wire it exactly as from the factory. That one wire that should go to BCM relates to the keyless access (dont ask me how it is connected, i didnt have kessy, but read in the same topic at ross-tech I think). I tried to put 12V to the charger before the installation to test it and it didnt work at all, but I read somewhere that these chargers work on the basis of CAN signal from the infortainment - it must be connected. Fortunately, it worked.

Frankly, I expected a little bit more from it. I use the wireless carplay adapter, too (carlinkit). When using wireless carplay and charging at the same time, the phone (iPhone 12) didnt charge very much, even not at all sometimes and it got quite hot, but at least it was not discharging. Now, I dont have this feature, though the world without the wires is great, however, the wires always work :)

You have more patience than I do lol. That's great. It's definitely a nice-to-have feature as opposed to necessary. My iPhone does charge, but not too fast. I have also tried an iPhone 8 and it charges like crazy, at least 1% per minute. The 12 Pro Max has a huge battery compared to the 8 so maybe that's why.

Since you had the wiring done properly, were you able to charge your phone when the car is off? Just curious.

Charger is definitely giving some juice to the phone, but it is much more effective when using just Bluetooth connection with the infotainment. I wanted that mainly because of the wireless carplay. So if anybody is thinking about it that way, I think it will be a little disappointment. But as you told, nice to have feature.

No, the charging went off after few minutes.
