Outstanding!

I tend to change them according to what I am listening to. You can access the EQ screen immediately by just pushing the right-side **** (or I can anyway - assume yours is the same).

You have to connect the phone to the car's OEM USB connector. In our Cayman it is in the glove box - yours may be someplace else. As soon as you plug in, Car[Play should appear. Bear in mind I know zip about Apple, but that is how it works on Android Auto so I am guessing it is the same. Bear in mind that the car OEM USB may not have enough juice to charge the phone fully while running CarPaly at the same time, so your phone's battery may slowly discharge.

Your backup camera is running off the CANBUS. You don't need to connect any more wires (and it is not recommended to hook into the reverse light circuit anyway as that is now 'old school' and can cause its own issues). If the camera is showing an image when you go into reverse, it is working OK. If the image itself is grainy etc, then you may have a) a poor camera with lowish resolution or b) you may need to change the camera settings. How you do this will depend on your camera, but on mine, there is a settings icon on the screen you see when backing up.

You can get sound from the rear speakers, but it will only be a 'copy' of the sound from the front L&R as the MOST box is 2-channel. Go into the sound settings and look for the screen where you can set the DSP etc. Here you will find a fader. Play with the fader so that you get most sound from the front speakers and some sound from the rears. That's how I have mine set as I like a bit more 'three dimensionality' to the sound. There are rumours of a 4-channel Russian MOST box, but I have tried to find one without success. In any case, if the HU only outputs 2-ch, I can't see the point.

This is the 'bright lights issue'. Andy refers to it in his reply. You need to apply the CANBUS software update to fix it. Instructions are just back a little in the thread. If you mean the 'panel lights' on the HU itself, you can adjust screen and panel brightness in settings. But you must do the canbus update to fix over-brightness in the OEM warning lights etc.

Agreed! A great way of 'modernising' the car.

If you use Waze or Maps for nav, you may have to go into the Settings and tell it which voice assistant you want to use. You will need to select Siri. Also, somewhere in the HU settings, there is a place where you have to tell the HU how to use voice assistant. I recall having to download Google Assistant to the HU to get 'ok Google' to work for me. Maybe you have to do the same with Apple? Just a thought.

@ZedZed

Thanks so much for the reply.

-Ok ill look into the Canbus update here shortly!
-Noted about the camera, i mean it works, im just begging at this point haha.
-Ill check the DSP settings. Again, the sound is still great out of the unit, so thats a plus!
-I tried plugging the cable into the OEM USB in the glove box and nothing happened.. hmmmm

ZedZed

You're welcome! When my wife brings her Cayman home from work, I'll have a look and give you the settings fo the DSP fader thing.

No idea why plugging in to the OEM doesn't give you wired Carplay. But then I know SFA about Apple stuff and just assumed it would work the same way as Android Auto. What's nice about the way AA does it is that I can plug my phone into my wife's Cayman and get all my own Android Auto stuff instantly, with all my settings, apps, music etc, and she can do the same in my Panamera if she plugs her phone into that car's OEM USB. It makes it real easy to swap cars and still have our own AA setups without all the faff of disabling Bluetooth so the 'wrong' phone doesn't connect or pairing mine or her phone etc each time we swap cars.

Someone who has CarPlay should be able to chime in and explain how to get wired working. If your main reason for not using wireless is that you feel you will get better sound quality with wired, you won't. CarPlay and AA use wifi for music not bluetooth so the SQ is as good as home streaming and if you have a hi-res streaming service, you won't get better by wiring in your phone. Bluetooth with CP and AA is only used to make the initial connection - once connected data is streamed via wifi. I would agree with you if the music was streamed via BT, but it isn't.

RwdConnor

Interesting, however i do still have thoughts on the wired vs wireless.

(Take this lightly, im no engineer)

My assumption is that Wired, no matter WHAT situation, will always provide a better quality. Think analog stereo setups, perhaps using tube amps/DACs, etc. The quality over wireless is limited by whatever wifi module they use. My assumption is that in all my previous cars, wired has always provided me with noticeable sound differences vs wireless. (This is me being extremely nitpicky on the topic lol)

Truth be told, the audio sounded great last night when i was sitting in the car for about 2 hours just playing with the unit (Havent had an android unit since the early mk6 vw days... good ol EONON)

The fun part about having an android is that it brings me back to the iphone jailbreaking days, can do whatever i want and customize it.. fun.

ZedZed

^^^^

If your earlier cars were streaming via BT then the sound would definitely be inferior to wired. But hi-res modern streaming services like Tidal etc are superior to CD quality, and in a car environment that is more than enough IMO.

HST, wired ought to work for you, so hopefully an Apple user can chime in.

RwdConnor

Honestly man im just being nit picky on things that dont really matter due to the 3.8 just a couple feet behind me lol.

I did however, go and try to update the Canbus via wifi and it was greyed out. Im assuming maybe my unit came with the newest latest and greatest.

Tried to find the DSP settings (i couldnt) hmmm

ZedZed

Haha. Yeah, that sorts most things out for sure

Could be since your unit is newer than ours.

Go the Equaliser first.



Then hit the surround tab




Then the sound field tab




Then play around with the controls and see what you get.

Do you lose the native TPMS when you switch to the Erisin unit?

ZedZed

No.

EDIT: to elaborate - the multifunction display (MFD) to the right of the tacho continues to work as before. You will still be able to get the TPMS display there. Also, you will be able to see the 'vitals' info for temp, pressure etc, and the trip screens, plus sport chrono if you have it. What you will lose from the MFD are the functions that came from the PCM 3.1 - satnav, radio station info and call info, because the PCM will, of course, no longer be connected!

RwdConnor

Ok well the rear speakers do in fact work haha. Theyre just alot quieter than the fronts (i mean... duh)

Just spent about an hour driving around with the car play and back up camera and it has totally changed the feel of the car, for the better.
I didnt HATE the stock PCM, but the ability to have carplay and a backup camera is such a must for me after leaving my 2018 Audi S4.. still adjusting
I have no regrets with the Unit at this point, truthfully, I do however, still wish i could use wired car play.. Wireless basically stops me from being able to look something up in a parking lot on my phone because its using the wifi signal from the unit.. Grrr

Anyone want a BRAND NEW Isudar 3.1 PCM kit.. its like $60 to send it back haha

ZedZed

I'm sure that CarPlay must be able to work in wired configuration. There are a ton of users with these units and using Carplay and surely someone must have tried wired? They can't all be using wireless?

Your alternative of course is to use the HU in 'native' format, where you download your apps onto the HU directly from the Google Play store and run everything from your Launcher of choice (CarWebGuru is my favourite, Agama is Andy's - there are others too). This has various benefits: you get the full version of the apps, not the cut-down Carplay versions; you can watch YouTube, Prime, Netflix etc (when you're parked up waiting for someone, obvs); you can run a browser on the HU, along with any apps that you can download from the Play Stire; you can use your phone in the parking lot, as normal.

To use the HU in this way, you will need to turn off CarPlay (or it will try to grab the BT and wifi connections) and then establish a hotspot on your phone for the wifi connection. I have automated this using an automation app like Tasker (there are several others) so that as soon as the phone's BT detects the car's BT, it turns on the hotspot. Establish a connection between your HU and the hotspot the first time, and ever after it will fire up the wifi on the HU every time the hotspot comes near, all automatically. You can set the HU to run your favourite navigation app automatically too, so by the time you have settled into your seat and put your seatbelt on, everything is up and running. Everything will be running directly off the HU if you go this way - no need to wire (or wireless) your phone at all. In fact, no need for a phone if you put a SIM into the HU.

The above is how my wife uses her HU. I was surprised because I would have thought that she would prefer the simplicity of Android Auto, but she prefers the full versions of the app and has no problem with switching between navigation, DAB (satellite) radio and YouTube Music. In my Panamera, I use Android Auto as the widescreen unit in there lends itself nicely to the AA format. Give it a try - you may prefer it.

(Apologies if I am teaching you to suck eggs above - if you are into jailbreaking/rooting phones, I am sure you don't need instructions on how to set up a hotspot LOL! I try to give a full rundown for the benefit of others who may not have your knowledge).

@RwdConnor Does your original USB work e.g. connect to the head unit if you insert something basic like a memory stick? Just to make sure the USB is actually alive and working...

ZedZed

Good point, @RwdConnor - did you connect the yellow OEM FAKRA plug that originally went into the PCM into the connector on the Erisin HU?

Here's two images that show what I mean.

PCM - see yellow Fakra for USB:




Plug that yellow USB connector from the PCM into the HU where marked:




That's an easy one to miss. I don't think it's in any instructions anywhere. No need for an adapter cable - the OEM yellow Fakra plugs right in.

This could explain why wired CP isn't working LOL.

RwdConnor

See this is why i love forums and have used them for almost 2 decades... I never plugged that FAKRA cable in.... Let me do that and test!
