I'm working on getting them uploaded to my website as well. If you like you can always reach out yo me privately and I can walk you through it.

 

If anyone is interested in buying one of these brand new Mr2Volt units for PCM 3.1, please take a look at my recently added classified advert. https://rennlist.com/forums/market/1401047

This unit was purchased this week and I made an error and purchased the wrong unit. Seems I have the most basic of systems and this is not compatible. Should have asked more questions before buying. Never installed. Just opened the outer shipping materials.

I have a Mr12Volt in a BMW E92 and rate them highly.

Best wishes,

 

I remember seeing someone installing the Mr12Volt system in their 981 and using an extension to keep the SD port accessible for firmware updates. If the person reads this post, I have some questions:

1. Where did you place the box? As shown in the last pic of post #2?
2. How did you end up routing the extension?

Thanks in advance!

Edit: Ok, I found the link to the post. See https://rennlist.com/forums/981-foru...l#post19309915

I am still wondering where the controler box is located to make the cables appear in that location. @CruisinUSA , could you please tell us more?

 

And another question: Since I bought my system from Mr12Volt directly instead of @Roman ACS and my 981 Boxster S came with XM radio, my spacers/standoffs are too short as many others noticed and there seems to be no place to route the cable since the XM antenna blocks the path recommended in the install videos.

Does anyone have any suggestions for fitting spacers and where to route the cable?

 

Does this work with non-PCM units, like the CDR 31?

 

Nope

 

I have a question for everyone who is currently using this system with an iPhone. I have the PCM 3.1 in my 2014 CS. I am not a person who is generally stuck on CarPlay. I am usually just fine using Bluetooth to listen to music and podcasts in my cars. Unfortunately, in the Cayman, when I am listening to my phone via Bluetooth, I have to turn the volume way up. Then when I start the car the next time, my FM radio comes on and blasts me. It usually takes about 2-3 minutes for the car to connect to my phone so I can switch the source and turn back up the radio to start listening to my phone again. I usually just end up putting music on a USB stick and listening to that, so I don't have the issue of the loud music and waiting for connection every time I get in the car. But the USB doesn't let me change up my listening content very easily.

If I were to get the Mr12volt system, would this eliminate this issue, or is there still a disconnection and reconnection issue every time you start the car? I just want to get in, start the car and have the phone connect automatically and start playing my content. Just like my other cars and headphones do. I am hoping that if I use the Mr12volt CarPlay, it will start in CarPlay every time I start the car and connect to and play from my phone without me having to take my phone out of my pocket or having to touch the PCM unit.

 

depending on how you have your phone set up your carplay or Android auto will start loading as soon as you pull the door handle. In my situation if I'm on a phone call the transition is almost seamless. If it's just music then I have audio playing by the time I turn the key.

 

The issue of PCM defaulting back to (high volume) radio was driving me nuts. I got one of these Firefly DACs and it works great:

Hi Roman

i have a 2015 Cayman incoming and want to add CarPlay. The spec says it’s CDR31 but at the bottom of the sheet it shows a part number for PCM.

Will it work in my car?

 

I believe that's still a cdr unit. Check if you have Navi. If says "aux" will on the button it's a cdr.

It has a button with CD Aux

 

CDR FOR SURE

 

So that means it won't work?

 

Is all of your steering wheel buttons working? My diamond button doesn't work and answering call button also do not work. Volume and mute buttons work though
