The joyeauto unit needs aux. Is your pcm3.1 unit aux activated? Check out posts 15 and 22 on this thread: https://rennlist.com/forums/997-foru...install-2.html

if you can enable aux and select it, then see if this issue goes away. If not you may have to activate aux .. but I don't think you need to buy any cables as mentioned in that thread as the joyeauto harness has the relevant wires...

 

Is there any other solution maybe, could it be wired somehow so that it doesn't use aux output for the sound? Someone told me to install FM modulator that gives an aux input connection.. don't know if thats possible on my PCM unit..

 

Have to have the Aux to play sound from Joy. I personally never use the sound from it, just visuals (wayz). All while listening to XM from PCM.

 

UPDATE - My iPhone took iOS 14.4 last night, so I tested a wired connection to the unit with a device on 14.3 and it worked as expected. My iPhone 12 Pro Max on iOS 14.4 is not allowing for touch screen input with the Joyeauto unit. Did a hard reboot on the phone and it appears to have resolved the touch responsiveness..... I'm still running the @konkab build from above that fixed the resolution issue. Has anyone else seen issues with iOS 14.4 and the Joyeauto unit?


Installed my Joyeauto retrofit in my 2014 Cayenne in April and have had no issues until today.

I'm in Michigan, so it's now getting pretty cold (10-20 degrees Fahrenheit). After about 1.5 hours of driving with the heat on, I noticed that the PCM touchscreen became somewhat unresponsive. The whole left-side (driver side) apps buttons would not select from touch or respond to the turn dial control, but I could still tap within Google Maps fine, just couldn't switch apps. I turned off the car, restarted, reconnected, same thing...but now the whole touchscreen within CarPlay was unresponsive to touch and turn dial control. What's interesting is that before my iPhone connected wirelessly, I could tap around within the Joyeauto menus without issue, but as soon as I got into CarPlay, it stopped responding to touch. Normal PCM menus work fine as well.

Has anyone seen an unresponsive touch screen in CarPlay with their Joyeauto units?

The unit itself is positioned behind the PCM, but it sounds like installing behind the glovebox or under the steering wheel may be better options...especially for situations like this. I'm wondering if having the heat on is having an impact on the Joyeauto unit. Anyone else see touch issues in colder climates with the heater on?

I'm going to give it some time to cool down and try again, and also try with some other iPhones (mine took iOS 14.4 last night).

 

I'm just North of Detroit, I'll mess around with mine today (also Joyeauto) if anything seems weird I'll let you know.

 

@ ZIP If your joy unit is behind the PCM that will make it hard to calibrate the screen in the future. There are some toggle switches on the joy unit to set various function. One toggle brings up a calibration screen on the PCM after you reboot the unit. I had to calibrate mine at install time. I installed mine under the steering wheel area and it fit fine there. Good luck.

 

I did calibrate it when I installed, but haven't needed to since.

Would be interested in seeing where others have installed specifically under steering wheel, etc.

I think my issue above was iOS 14.4, so luckily it's not a heating issue...

 

Mine is actually to the left of steering wheel - right on what I think is the main harness

 

Hi just installed joyauto but I have to press the button for joy auto to start, is there a way to initiate joyauto and CarPlay automatically?

Also I am receiving this static from joy auto aftermarket camera, any ideas?

 

2017 is first year based on research I did when buying my 17 CSehybrid. It works only when you have phone plugged in. I believe starting w/ the 19 and newer models it works over the air.

having car play was a requirement for me, that’s why I looked at model years starting with 2017.

 

I have 14.4 on my 8+ and I haven’t noticed any weirdness at all, and I’m a few hours northeast of you. Did it resolve itself?

 

Haven’t seen the issue again since the reboot. Weird.

 

Check your ground, connections then if possible connect a new camera to the back of the radio temporarily to test it.

 

Hi
What are the correct BT settings to make carplay work seamless on Joyeauto (Cayenne PCM 3.1)
Currently I have to go to my phone's BT and select joyeauto to start carplay after starting the car - if I press navi is end up at the setup screen (I have the red wire wired in parallel to the existing PCM fuse (51))
I am confused how to connect the BT - Do I need my existing phone to PCM BT connection? or should it be deleted?
Should the carplay unit be paired to the PCM?
Everything seems fine most of the time besides from not auto connecting when powering on the car
I am on IOS14.4

Any ideas?

Thanks

 

Hello, tried to install JoyeAuto on my Cayenne but screen is blue and faded on CarPlay interface but also on original menus... when I remove JoyeAuto card, all become normal again.. hardware default or installation error ? :/
