There's a new kid on the block

£214.78 21%OFF | ISUDAR Carplay Module For Porsche/Panamera/Cayenne/Macan/Cayman/Boxster 911 718 PCM 3.1 Android Auto AI Box Camera Multimedia

Thoughts? Looks like the external box is not a requirement and it now has DSP and apparently improves on audio.

This actually sounds interesting. I need to do more research on it. If it still uses the AUX connection as the main source for audio, then is as worthless as the current generation. But if it integrates the USB connection somehow, bypassing it without processing the sound, but allowing apps like Waze to send audio through it, then that solves a lot of issues with current gen. I’m tempted to buy it to test it. If anything, it will allow me to get rid of all the cables and the external box…

Check out the install video, no sign of an external box and the antennas (two of them connect directly to the board fitted inside PCM.

Assuming both the ISUDAR and EBILAEN modules are the same thing? They look the same. Which of the two companies had been more responsive answering questions?

Hi Santirx, do u use the factory usb plug to plug in your usb stick?

i want to do this upgrade. but i believe my usb plug doesn't work cuz something was spilt on it previously...
No. I used the USB input to the CarPlay module. I brought that connection to the Center Console, with a “factory-like” plug. If you see the video, I’m plugging the USB drive towards the front of the center console box, and the factory one is located towards the side.

Did you install the Ebilaen or Isudar CarPlay module?

I have no modules installed. I just fell down this rabbit hole this week.
initially I contacted a guy on Facebook who does the updates to pcm. Then was Told the 3.1 he can’t do. But that update uses the USB for wired CarPlay so I’m SOL cuz mine malfunctioned.

after a weeks of trying to understand stumbled and finally ended up with this thread and look promising.

Yep.. you need either a Joye module or an Ebilaen/Isudar type module, which you need to install inside PCM in order to add CarPlay to PCM3.1. There is plenty of documented procedures on how to do this DIY.
Yes thanks. I guess my initial ask was just about the USB , if it used the car’s USB to do updates and wired CarPlay etc then I’m doomed.

glad to know that there is a USB do these upgrade units, and I can proceed.

so, u would recommend the latest one? Ebilaen?

... Now, for the review….
The Quirks (so far):

1. When in iPod mode and using CarPlay over WiFi, I lose the ability to control volume with the head unit volume knob. However, the steering wheel volume knob works well. Fortunately, this is not an issue, as I have both the steering wheel knob and the Helix Conductor to control volume. I think this is due to the fact that the Ebilaen module takes control of the head unit volume control for CarPlay and it wants to control CarPlay volume when you are actually with the iPod.

Hi - I just discovered this forum and thread. I was researching others' experiences with the iSudar/Ebilean solutions and that search led me here. Kudos to all of you who posted install videos and so many other helpful comments.

I was going to pull the trigger and purchase the board until I read the bit quoted above, about the volume control not working when using CarPlay over WiFi. Now, I'm not so sure. I'm concerned the board won't work for me because my car doesn't have a multi-function wheel with a volume control. It thus seems if I buy the board and connect with CarPlay over WiFi, I'll have no volume control. Obviously, that would be a non-starter for me.

It's hard to understand how a manufacturer could market a board that disabled something as basic as the head unit's volume control under any set of circumstances, so I'm wondering whether anyone has sorted this out yet? If not, has anyone installed the board in a car without a multi-function steering wheel and, if so, does the PCM's volume control work in that instance?

Many thanks.

Hi, I think you may have misunderstood the actual issue. When you connect you phone through WIFI CarPlay and select AUX input, you have volume control through PCM volume control.

I’m using this slightly different, where I connect via CarPlay WIFI, but select iPod as an input (not AUX). That’s when I lose volume control through PCM which is what I was referring in my post above.

The reason this happens is because when in CarPlay, this board takes over volume control through AUX. The preference would be for the board to relinquish volume control to the PCM, that way both steering and PCM volume controls would be in sync. With this new module, the steering wheel and PCM volume controls get disconnected from each other when in CarPlay.

This module should work well in your application/configuration, if you select AUX as your input.

There is someone (coder) in Rennlist who just installed the board (he had produced firmware updates for Joye successfully). He will most likely produce a firmware update for this resolving all these quirks.

Any further feedback on aux BT audio via OEM and carplay via module? Tired of wasting my burmester speakers on chitty joyauto aux.
No issues with AUX BT so far with Ebilaen/Isudar module. It seems to work very well with no interference. I have left my AUX BT on for more than a week now and no issues. I don’t intend to turn it off and I’m actually leaving it as an option.

Question - did you get interference/hissing in standard form using intended Aux? I'm trying to remember if I always had interference/hissing prior to modifying cable to route audio via aux to usb adaptor.

I know factory AUX setup (when not using CP module aux) there is zero interference/hissing. But I can't for the life of me remember if I had the issue before I messed with wiring.


I'm starting to think the solution is to disconnect the ground wire going to the CP module board, only because the interference/hissing starts when car is started and changes pitch with AC fans switching on.

Quick question- I have a NetworkWWS adapter which has decent sound quality (for those of you with buzzing, make sure you don't have a loop in your wiring around anything that carries power as this will cause alternator whine) but no support of track skip/advance in either AA or Carplay. I was wondering if this single-board iSudar setup supports the PCM buttons on the faceplate for controlling audio sources via Carplay/AA. I know Joyeauto does. Also, for those of you on Android, I have an AAWireless adapter that plugs into the USB port, and one feature it has is 'BT audio sink' which reroutes audio from Android Auto to A2DP Bluetooth audio. In its current state it does not pass along Google Assistant or Maps voice prompts but they say they'll look into it. I will keep people posted on progress if that is of interest. Thanks!

Yes you can control from PCM3.1 to skip tracks etc..


The white noise and interference noise videos are here:


One video is with android auto connected via USB cable, I get a white noise but only at close to max volume 80%+.

The other video is android auto connected wireless, you can hear the WiFi interference, mostly noticable at volumes 60%+.

Not sure if it's the wiring or something I have missed.

I successfully installed the ISUDAR system in my '16 Turbo yesterday. I had to make a trip to the hardware store since the included standoffs didn't leave enough clearance for my Sirius module but that was the only surprise.

I'll agree that audio quality is much better when using AUX BT, but then you lose Siri and navigation audio so I'll probably just stick with AUX for the most part.

Thanks to everybody in this thread for the information. @Santirx maybe I missed it but where did you mount your microphone? I tried getting into the overhead console but was afraid of breaking something so I just stashed the mic at the top of the A pillar for the moment.

I just put it on the trim under the steering wheel column. Used double sided tape.

I received the module from ISUDAR. ordered via their website direct, not aliexpress.
I have to buy the vent pullers before attempting the install.

  • is it correct i do not need to use the lengthy mic wire? if so do I just leave the female mic as is?
  • i received 6 standoffs. would this resolve the clearance issues?
  • do the FFC cables go in only one way? i can diy mechanical things but i rarely touch electronics.

Thanks in Advance.

But here is what I received:


Smashed box
245762
245763


245764


245765


Not sure if it matters but noticed the board is ver 1.2

ISUDAR module was installed last night. Just wanted to add some observations to help the next guy like you all helped me.

- What a pain to pull out the vents. left came out as instructed, but i did manage to snap a small tab. did not notice till i put it back together but it went back in fine.
i had the entire passenger length trim panel dislodged but the final lowest vent clip by the stereo refuse to come out. but with brute force it finally dislodged.

Here's a few items that differ from the previous installs:

the Sirius board has a GIANT green plug that is unlike any of the others posted here and online:
Image


ISUDAR sent 6 Standoffs, 18CM. i thought i would be enough as Don16 used 15+20 for his install, but my sirius board/plug is different.

I ended up using 20+20 in order to have the ISUDAR board clear. i don't think it clear but most likely it rests on that plug. I'm from canada so maybe the canadian board is different i dont' know.

Image


Field Level View - that's a 20+20 Standoff on the right:

Image


Note about plug direction: the pins are on the bottom so your plug should line up with the holes on the bottom:

Image


I had a hard time removing the CD, so i just undid the 2 FFC to detach the screen. it made everything easier to do and flat surfaces to work on. this also allowed me to fish the 2 screen FFC's only through the outside holes.. probably not necessary but give the cable a bit more slack.

Image


Like all typical car stereo metal, it is SHARP!... i while fishing the FFC's through, i keep scraping my fingernails. As a precaution i taped up the edge so it won't scrape/cut the FFCs:

Image


Note I didn't need to fish through the 'inner casing":

Image


As with all DIY always encounter something new, so i hope this would help future installers with my board and problems.

Last Notes:
  • i just taped up the open mic and speaker wires 'just in case' of interference / noise.
  • i didn't need to install the mic. in the settings turn on 'use original mic' and it works fine.
  • aligning the bottom cd cover flap was tedious. I didnt' know what i did wrong but there's a certain 'fit' that need to happen but after 20 min of fidgeting i finally had it in the right place for perfect fit.

Cheers!

@nsx88, thanks for the added information. I will perform this upgrade when my kit arrives.
Question, are you experiencing any “white noise” or Wi-Fi like noise artifacts when the volume is up relatively high ?
How do you like it’s operation so far ?
Cheers!
observations so far (i'm not an audio /electronics guy by any means):

1) it says turn on wifi and bluetooth on the phone. then in the module menu go to "wifi carplay settings" - and then connect using bluetooth and pair the phone.

[what i don't understand here is why it's in the "WIFI" menu, but connecting using "Bluetooth". it also has a 'Bluetooth" menu, but i can't turn it on/off in that menu and nothing is selectable on that screen.]

in any case, i'm connected via bluetooth to the module as far as i understand ( my phone shows its connected via BT and not via WIFI) and is using the AUX input to the pcm.

- i've taken a couple trips, and i've had the carplay disconnect a couple times this weekend. the first time it didnt' reconnect itself. the second time it happened it reconnected after a minute.

- also, there has been one or two times where there was lag. screen lag and sometimes a couple seconds where it's freezing/ pausing when i'm just simply switching apps etc.

- there has also been multiple times were there's interruption.. like someone's walking away and getting too far with the phone and about to disconnect. even though i'm just driving as normal and the phone is in the cupholder.

- in this default connection mode, i do not hear any white noise.

- one time, i used my phone and manually connected to the module via WIFI. in this mode, i couldn't hear the music play through the module but the carplay on and working. when i turned it up, there was noise/hissing.

that's all i have in terms of usage so far. i think it's working ok 80% of the time.
i also kinda smushed the thick rubber coating on one of the antennas while trying to put back the stereo... but i don't think i damaged anything.

maybe someone can explain/clarify the difference between wifi and bluetooth connection? 'm not sure.

I purchased an Isudar CarPlay module when I though I had bricked my Ebilaen module. My Ebilaen module is now fine (just required a long power cycle)… so, I ended up with an extra module (could not cancel order on time).

The board version is 1.2 (latest one). Everything is new (wasn’t installed).

If anyone in the New England area is interested, I’ll give preference to these offers.

I paid $310 after currency conversion.

I’m willing to sell for $310 with local pickup preferable. But if anyone is interested in getting it, you just have to add shipping costs.

The advantage is that you won’t have to wait until this ships from China and you won’t have to wait a couple of weeks to receive it.

Working with @Don16, we were able to figure out how to improve the audio quality when using AUX and the CarPlay/Android Auto Isudar module for PCM3.1. Historically, it had been the main issue for this CP/AA module implementation. The AUX quality was simply not good enough, order of magnitude worst than when playing via AuxBT or wired iPod.

With the modifications we made, the audio from AUX is orders of magnitude better, resembling very closely the audio from iPod or AuxBT.

What we discovered through a lot of testing is that the culprit of the audio quality is not the Isudar (or Joye module for that matter), but the PCM Aux itself, which is a bad implementation from Porsche. To reduce the influence of the PCM Aux, what we did was reduce both the PCM Treble and Bass settings to -6 (the minimum). Obviously, this will cause the audio to lose tone/output at low and high frequencies. This is then compensated with the Isudar module DSP and its 16-band equalizer. It really does a great job at enhancing low and high frequencies without adding distortion,

I was able to tune the system basically using the Isudar 16-band equalizer, and the audio now coming from AUX in my system is nearly at par with AuxBT/iPod. Very hard to hear the difference.

This is how I started, after lowering treble and bass to -6 and adjusting 16-band EQ by ear (teal curve is the Harman reference curve, which is the standard for car audio tuning, and the red curve is my system response).

Image


Image


This is how I ended up after tuning with the 16-band equalizer using my calibrated Umik microphone.

The result was superb. Sound quality from AUX is order of magnitude better.

I'm not sure if I will use AUX for my normal commute. I will probably continue to use iPod or AuxBT. But now AUX is a real option when I have to use Waze for navigation.

The important thing about this experiment/test is that anyone with a Bose system can use AUX, reduce PCM Aux influence on audio by lowering treble and bass to -6, and then use the Isudar module to tune the system to your liking. The Isudar DSP and 16-band EQ really expand tuning capabilities of the OEM system. It is a good option vs the treble/bass option in the PCM.

Anyone not able to change SOURCE after installing the Isudar (or others)? I am stuck on FM radio, but can't hear anything anyway. SOURCE button just takes me to a System Info screen that tells me System version: v4.75, PCM3.1, Serial Number XXxxx, and has buttons for "Current system" and "History". Otherwise I'm able to connect to CarPlay without issue. Unfortunately with the current situation I've also lost the ability to listen to music via radio, bluetooth, etc. as well as making calls.

hey folks - are people ordering directly from the isudar.com or from the xyingly.com that was linked in don16's video? isudar.com doesn't have the preorder for the new module that xyingly is featuring (it's $320 instead of $285 and apparently has a new DAC and op-amp). didn't want to deal with the external box in the older joyeauto version, but this new boxless variant is looking pretty good to me...
