1) I accessed the unit under the carpet and the USB extension wire -- which normally my Apple Lightning cable is attached to.

2) I formatted two jump drives a few times using my Mac (I tried both MS-DOS and ExFat), as for whatever reason the unit couldn't find the ISPBOOOT.BIN file. I did confirm that "USB" in the main screen (where it showed Android, CarPlay, etc.) lit up in blue, so the USB was working. (BTW...As the System says USB 0 and USB 1, is there a second USB connection I'm not aware of?)

3) Eventually (I'm not sure as to which PC-based formatting I used), eventually it did in fact "see" ISPBOOOT.BIN and it asked me if I wanted to upgrade doing a complete upgrade. I clicked "YES" and the screen went black. I know that black screen was only supposed to be that way for 1-2 minutes, but we're talking over 5 minutes in this case with absolutely no change.

You can imagine that I was trying not to freak out, as I didn't want to brick my unit...especially as you NEVER, EVER want to interrupt a firmware upgrade. Long story short, after 5+ minutes -- I shut the system down and restarted the PCM. THANKFULLY, it wasn't bricked and CarPlay showed up again. I tried again, giving it a solid 3 minutes...but still no luck.

Any thoughts/suggestions, please let me know.

Initially I was thinking nmautomotive, but is that one slower and not as good of a display? Does the nmautomotive unit have better sound quality?
$330 for the joyeauto vs $650ish for the nmautomotive is a huge difference and not sure the cost is justified?

I guess I don’t fully understand how the audio part works. iPhone pairs with the unit via wifi to transmit the display, and then do you keep Bluetooth on the phone connected to the pcm to play audio through the pcm? I mainly listen to Sirius or Apple Music. Not sure if anyone could chime in more specifically on that please?

Thank you in advance for any direction.

I haven't received the vehicle yet, but proactively gathering information so I could get this installed for when the car gets delivered (hopefully next week). It's a CPO vehicle so I also wanted to seek your advice to enquire whether it affects the CPO warranty. Thanks in advance for your help.

The update drastically improves smoothness of CarPlay experience by 2x and activates 60 frame per second capability instead of previous 30 FPS. It makes CarPlay much more responsive.

It's based on the latest original Joyeauto firmware from 2021-03-26 and includes all my previous fixes. I flashed the firmware on my unit, tested it and can confirm it works fine.

2021-5-10.custom.v2:
- Enables 60 FPS CarPlay capability

Use at your own risk.

After firmware upgrade your settings will be reset to default. To restore your settings, you'll need to:
1. Go to Settings -> Carplay -> Enter 1123 -> Select Porsche
2. Go to Settings -> Smartphone -> Reboot
3. Setup wireless CarPlay again.
4. Restore other settings like EQ, Display, etc.

Our unit (NM Automotive) and the Joyeauto unit utilise completely different hardware and software. Obviously, they both work, what we would say is our unit is better integrated with the car OEM systems, the screen responsiveness is crisper and the sound quality is better. We do have a good number of customers who have switched from Joyeauto to our kit. Predominantly, we sell our kit because the support from the manufacturer and our support to customers is better than Joyeauto offer. But with all these things it's down to customers to make an informed choice as to what they are looking for from a product, in this case it's lower price with limited support or a higher price for a better product with better support. We don't think there is a definite right or wrong

Thanks

Thanks!
