Hi @Santirx! Could you take a high res 60 fps closeup video of CarPlay interface and share it on a cloud? I'm considering switching to this unit, but would like to see how smooth and sharp the interface is.

 

Check this. Let me know if this works. I recorded in 4K and 60 fps

Thanks for the video. I see some improvements in image quality like better chroma subsampling and image sharpness, but it looks like it's still not perfect. Also image bit depth looks a little low and frame rate is not 60 FPS yet. Overall I would say the image quality is comparable to Isudar.

Better chrome subsampling (no blurry edges).

Low image bit-depth.

 

Thank you @Santirx for this thread and the extensive installation vids/posts. I was able to install in my Panamera in one evening and everything went smoothly thanks to your guides.

Being able to order the Amazon 3.5mm cord for the factory mic and add that in at the start made the overall experience much better. I had been hesitant about having that aftermarket microphone bobbing about and went through with the purchase after I discovered your solution.

 

Hi Santrix, thanks for all of your DD on this topic.
My Isudar is coming out today, the Aux sound quality is literally unbearable. Aux BT is fine, but Aux input must be selected to get voice on Waze or Google maps. Attempting to have Waze fully functioning means I simply “can not listen to music at the same time”. I was told I have the latest board and software when it was shipped to me.. Now Kimi says an “update may help”… Frustrated and disappointed.
have the bugs around “popping” in Mr 12V’s product been addressed?

 

They are being addressed. I don’t think it would take much longer. You might want to ask Mr12Volt directly before you buy. They are best reached through their WhatsApp link.

 

Excellent. Thanks for the feedback. Glad you were able to use my videos to complete your installation.

I agree, the mic solution is a must have. I can’t stand the aftermarket mics either. Mr12Volt should implement this solution in their product, as it is really an easy add-on.

 

I’ve had this product installed for a few months now after research here and Santirx great posts. I don’t have the same popping issue described here but I am getting concerned about battery drain. After the car sits overnight it’s getting increasingly difficult to start. My battery is new within the last few months but something is draining it and I’m guessing its Mr 12volt. Has anyone else experienced this? I’ve turned off some settings such as “autostart the app” to no avail. It’s a really good product and love having it but worried about this issue with the battery.

 

I have not experienced this @MJDore . What you can do is, disconnect the Mr12Volt from power and monitor power after sitting overnight. See if you still have same issues.

 

Thank you for the update. And thanks to @Santirx for exploring this new setup from Mr12v. It may just save my PCM from being ditched.
I had iSudar and it stopped working after a firmware update. I ordered a new iSudar board but had an identical problem with new board: black screen. The PCM itself still works. I even tested both boards with a different PCM which I purchased used, and same problem. I ended up buying the Mr12v board. I have high hopes and your post adds to the enthusiasm. If Mr12v doesn’t work I’ll go against my OEM-obsessed nature and opt out for an aftermarket stereo system (one of Tesla screen ones) and stop wasting money on these boards. It has become a headache and I can’t live without CarPlay anymore. PCM3.1’s Bluetooth setup is as dumb as it gets. Granted, once I took iSudar out, I realized PCM’s own Bluetooth sounded better.
Regarding battery drain: I confirmed iSudar was draining my battery such that after a couple of days the car refused to start. Without iSudar, no more issues. the car never refused to start. I will be monitoring Mr12v as well. I have an old battery which will not handle slow drainage well. I will post my experience in this thread.

 

One more thing: I wish Mr12V made a version that would fit in the PCM if one removed XM. I don’t care for XM. Neither do I care about cd drive if it wasn’t needed for update. That is plenty room.

 

Have you applied the latest firmware update? It addresses the issue where can wakeup would wake up the box. If you have a tracker (Porsche Car Connect) or similar that would be waking up can and in turn was waking up Mr12volt unit. They have changed this behaviour.

 

I have not noticed that yet, but as mentioned there is a recent firmware that prevents the wake from the CAN bus. firmware and change log can be found here https://www.mr12volt.com/pages/p2000...ftware-updates

 

I’ve been communicating with Mr12Volt about video quality. Even though I mainly care about audio quality, we have noticed some issues, like banding, on video quality. Mr12Volt responded in a few seconds… this is something they will be looking at.

Below is my communication and their responses, with some photos for comparison in WhatsApp:

Photo # 1 = mr12volt in my Macan PCM3.1
Photo # 2 = PCM4.0 in my Cayman
Photo # 3 = Isudar in my Macan PCM3.1

 

Thanks @Santirx for making the inquiry. LOVE how transparent and reactive MR12V is compared to iSudar= awful
Hope for an easy fix....then I am in !!!
