Only takes 1min to upgrade Carplay (W212)




If this goes well, maybe I'll tackle the torn seat cushion next

so I unplugged the large power connected that was supplied and replugged the factory directly into my head unit bypassing all the CarLink stuff and it’s working like normal. There’s an issue with the connected that is supplied, see the pictures below. Is this normal?

Carlink harness to factory harness. Note the set of pins on the left, no round ones.

A–Check the LVDS wiring is connected as per the wiring diagram.
A-Check that the pins in the LVDS connectors are not bent or not making contact
A-Check that the dip switch setting is correct. Try changing them . Make sure you unplug the box power each time a pin is changed.
Q: I don't have any sound ?
A–make sure the cars original MOST fibre optic cable has been moved to the new connector on the T harness
A-Activate the AUX from the cars engineering menu. Select AUX on cars audio settings.
A-If its not possible to activate the AUX you will need a AMI to AUX converter cable

I’m not sure what wiring diagram you are referring to, there wasn’t one included in the box nor could I find on the website. I followed the video that you emailed to me. Not sure which car that was one but there was minor differences. I do believe that mine is connected correctly.
There is no mention of a dip switch anywhere or that it needs to be changed. I believe it’s labeled the Toggle Switch. And if so, then yes it’s correct.

The hardest part was fishing the wires and pushing the HU back in place, but that's all been documented before in other postings so I was prepared
Anyway, imagine my dismay when I reconnected the battery and lo and behold, no sound even from the factory radio, and it was strange I could only access two selections on the menu screen. Quick research and emails to Andy at CarPlay helped me change some dipswitches. Make sure you know your car screen - mine had to be changed from the factory settings to 7" screen and NTG4.0 instead of 4.0S.
Also remember to wait 10-15 minutes for the residual power to shut down and let the module reboot and reset, changes are not instant. It was getting late that night and I had to work the next day, so I called it a day without sound
More online research revealed that my car has Harmon/Kardon sound - I didn't realize it, but there is an optical cable that must be transferred from the original harness, by separating that wire and plug directly into the headunit onto the new harness Quadlock.
Bingo!!! Sound was fixed. But I still couldn't access the screen settings on CarPlay strangely. More online research and emails to Andy at CarPlay - he was very responsive and helpful - and I realized the problem was actually on my end. My scrolling controller knob in the armrest needed the dreaded and common repair. Luckily it is available in aluminum from Amazon for $10 and I got it shipped the next day
That silver circular piece was tricky to slip off
The broken plastic shaft inside the scrolling knob
The new metal shaft piece is definitely much better than the original plastic one. A very well-documented repair on Forums here, and on YouTube
So probably six hours total work including research and YouTube watching, but this works great and is a nice modern upgrade for a 12 year-old car
My favourite things so far are:
1. improved sound quality over the factory Bluetooth connection, less skipping and lag time
2. Google maps and Waze for real-time traffic info, which my old system didn't have
3. Spotify connects automatically and quickly with my phone, as opposed to having manually connect each time
4. Modern look and colour scheme
5. Good support from the supplier - very timely and he tried to help with tips on email (even offered to order the replacement control shaft for me). Did not get the sense he was dodging me, like other experiences I have had with different vendors over the years
Good luck to the rest of you who are thinking about upgrading with this, or with alternate systems. I think it's a good value for $300 and six hours of my life, it's about the same amount of time and money I'd otherwise spend at the golf course + cart fees, cigars, drinks and dinner with the guys afterwards
And also probably the same number of F-bombs dropped when stuff didn't go well the first time around

I have my iPhone paired to the unit and it shows up in the paired devices under the main carplay icon, but it is NOT showing up as a CarPlay device to use. That subscreen is blank. I've made sure and I have the carlinklife connected under my carplay setting on my actual phone.
Any idea on how it have my phone show up on the car side carplay device?
I've reached out to their support too, who have been in touch and told me to change my toggle switch settings, even though I had just figured it out.


I had sound from CarPlay for a minute, but I think it keeps losing the BT connection to my phone. I check my phone and it says it’s not connected to CarPlay. I’ll fiddle with it more tomorrow. It was getting cold and I needed to grab a beer and watch football.


What did you do to fix it? I feel like I'm close and the wires are all connected properly. I know there's no way I'm taking all that apart again!

A–make sure Carplay and wifi is turned on on the mobile phone
A-Clear the Bluetooth devices from the cars menu and the phone . Then pair and connect again
A-On the main menu select Wireless Dev , rest the Bluetooth then pair
A-Check and restore Mobile network on phone.
A-Check that the mobile phone Siri permissions are all turned on.
A–Check the wifi antenna is connected and not attached to Metal or the black box itself. (fit away from the black box)

After all that, I hit connect mobile device and paired my phone. It shows up as connected under Paired Device, but nothing shows up on the CarPlay Devices screen.
My phone connects to the black and white CarPlay screen (first pic). As soon as I pair my phone and it switches to the color CarPlay screen (see pic), the Bluetooth connection drops. Happens every time. The screen mirrors my phone, but I get no sound.
Could it be one of the dip switch settings, or would I get nothing at all if they were wrong?

Not sure if your car is NTG 4.0 or 4.5, but it looks like they still have it in stock.

Are phone calls handled through carplay or MB Comand? Does it use the stock factory fitted microphone or does it use the iphone microphone?
