If you're experiencing this issue:

I received a patch last night. YMMV:


It's an APK file..copy to a USB drive (or I guess download direct to unit) and then click on it from the file manager.

Thanks for the file. It worked in mine as well. But it seems to have changed the units to F. No functionality to the switch though.

 

They probably just hard coded the fix it seems. Ok for me since I don't plan to go back and forth between C and F, but good info for anyone else thinking of applying.

 

I guess mine already had that patch applied. I had "C" selectable. Good news they supplied a patch !!!!
We still waiting on several others.......

 

I wouldn't have cared if I knew the conversion of F to C in my head.., but growing up knowing F temps 99% of the time makes it hard for me.

 

@djbooya , when you press the Diamond (joker) button on your steering wheel, does it advance the sources on the 12.3 ? Mine does, super annoying. I have notified them. If yours does this as well could you let then know ? Hoping for a patch !!!!!
cheers

 

I sent them video already. It does the same thing as yours.. I want to re-program mine to go to next track..

 

It’s really a lazy coding fix though …….it should work for both.

 

I agree, but I'm happy they even supplied a patch at all!

 

I stand corrected… the F/C switch does work with the patch. Probably required a reboot, which I didn’t do immediately after the patch.

 

Where do we get the patch? Message them directly?

 

Do you guys get elevation data on your dashboard after the change to the new radio?

I used to get this coming from the old unit and assumed I would get it from the GPS data over the canbus interface (similar to how the compass is showing).. I have a report in with the vendor, but curious if I'm the only one that has this issue and something I need to debug locally on my setup (vs issue with unit/code).

 

There is no LVDS data coming from the new 12.3
Probably why . There is now no PCM, no NAV Data.

I coded out the LVDS line in the IC so I do not have the LBDS fault, that you most likely have .
No. Biggie for me

 

Where does the compass data come from? I was under the impression that was coming from NAV / GPS data from the radio? I guess not? Are you using PIWIS 3 or Launch or something else for coding? I'm debating on what system I want to invest in and may decide to pickup the PIWIS 3, but need to determine if its worth the $ for me. I have an Autel tool now (https://amzn.to/3H1oSST) for all the regular maintenance functions..

 

I think the Compass data would be picked off of the GPS.

 

That's why I thought the elevation data would make it back to dashboard as well since the compass data was showing... I assumed the elevation data came from GPS and not from the NAV unit, but maybe that's the issue..

 

Yeah, seems fine.

I just wired in the toslink to most adapter replacing the factory RCA one. No sound currently. Did I miss a config setting I needed to change?

 

Did you leave the wire harness connected? You still need power. You only disconnect the RCA connectors.

 

Strange..looks like audio is working but the button beeps do not go over optical it seems. Music seems to play fine

 

So no Canbus noises , seatbelt , etc ?

 

Let me double check..I thought I heard those...

No seatbelt sound, no door sound. What I heard was the parking sensors and when you leave car in drive and turn engine off reminder. Audio volume is much improved though so I will deal and report the bug and hope for the best.

 

So I finally got around installing my unit. Overall, the biggest challenge was cable management. It took me a whole hour to work out how to tuck all that mess in behind the unit.

After that was done, everything seemed to work mostly fine.

The MOST-TOSLINK box also works wonderfully. The sound quality is just as good as my previous unit, which had a TOSLINK port directly integrated in the back of the unit.

I also installed a USB DAB+ dongle, plugging directly to the DAB+ wiring of the car. And reused the OEM GPS antenna with a fakra adapter.

I haven't had the chance to test everything out, but so far, the only problems I've had are the reverse camera (no feed, probs a software configuration issue), and the diamond button switching sources in the unit (I have it mapped to some other car-related function).

So far, though, I am very happy!

PS: Just for info, I purchased two original 95B.2 side vents, in order to match the style of the new center vents. Unfortunately, I can confirm these are NOT a direct swap, and won't fit the Dainav trim. Perhaps with some modifications, these could be made to fit... but that's not something that I am ready to undertake. I might, however, look into fitting the silver metal trim from the new vents in the original vents. That should bring the style closer to being a match.

 

What magsafe charger is that?

 

I am having trouble finding the optical cables that plug into the blue box.

I believe I may the challenge mentioned above -

• The MOST adapter with TOSLINK port is NOT plug-and-play for this unit. That's because the non-TOSLINK box uses a 8-cable socket for the 12V, Ground, etc, while the TOSLINK box uses instead a 6-cable socket. As our headunit comes pre-wired for the non-TOSLINK box, it uses the 8-cable socket plugs. This, however, should be easy to fix by re-routing the cables to the plug that comes with the TOSLINK box. So minor modification required.

I have two green cables that run into the 8 cable socket box how are people handling this or am I missing something.

I basically have no sound but everything else appears to work.

I figured out how to get the two green cables unplugged from the 8 Cable socket box.

The way I fixed it was by replacing the 8-pin wiring loom coming from the headunit, with the 6-pin wiring loom provided with the new TOSLINK box. I did the following:

1. The 8-pin wiring loom for the original blue MOST box had five wires connected to it:
   1. Yellow (power)
   2. Red (accessory power)
   3. Black (ground)
   4. Red/black (left/right analog audio channel)
2. For the new box, we only need 1, 2 and 3. So we cut those being generous with the length, by cutting as close as possible to the connector connecting to the blue box (we will discard that connector at the end, along with the two analog audio cables for the R and L channels)
3. Then, we get the new 6-pin wiring loom from the TOSLINK unit, which should have three cables connected to it:
   1. Yellow (power)
   2. Red (accessory power)
   3. Black (ground)
4. We solder the three cables from the 6-pin loom, to the three cables going to the unit (the ones from step #1) by colour matching: black with black, red with red and yellow with yellow
5. After this, the wiring is good. We can now connect the 6-pin loom coming from the headunit to the new TOSLINK box. Important to understand is that these three cables only deal with the power management of the box. They do NOT carry audio.
6. When installing everything, an additional TOSLINK/SPDIF cable should be connected from the TOSLINK box to the headunit. This cable is the one carrying the audio. This cable was provided in the same package as the TOSLINK box.

With that, my unit worked without issues. Hopefully that helps.

Awesome . I have 2 questions on this Toslink setup.

1) in the DAINAV EQ , are you able to fade from full front to full rear ?
) Are you getting the Canbus alerts in the speakers ? Door chimes, etc ..

 

About the fading, I haven't tested. But I'd be surprised if that was the case. I think internally the protocol works with two channels only. But I can test it in the next days and let you know.

Regarding the canbus alerts, I haven't paid much attention. I did get, however, a chime warning me about "putting the gear lever in P position". So at least, that one did produce a sound without issues.

That being said, I suspect these chimes are independent of the headunit. I was getting them even while trying to install the headunit... and at that point, the only thing I had in the dashboard was a big hole. So no headunit at all

 

Excellent !!!! Cheers. Does it give 5.1 like this as well ? And fader : LOL !

 

Thanks for paving the way on this!
What features are eliminated by removing the PCM? I love the look and functionality gains, but does ditching the PCM effect anything else other than the GPS and NAV?

 

I think the biggest loss is the integration with the instrument cluster MFD: you won't see the map in the MFD, nor you'll get the information about altitude, etc.

Also, because the car isn't able to access the GPS maps from the unit, two additional functions are lost:

• The speed limit display in the MFD, which requires GPS map data (in addition to the data fed by the overhead front camera)
• The PDLS+ activation of cornering lights when approaching roundabouts

Other than that, I can't remember other stuff that is lost in the process. Perhaps others can chime in.

 

Thanks for the quick response. Given that i don't often use the nav, I see one of these in my future.

 

Honestly, you won't be disappointed. The device itself looks pretty OEM, and the main software also does. Of course it has some glitches here and there, as expected from every product from AliExpress. But so far, nothing that couldn't be resolved. The community here has been of massive help.

I personally recommend it.

 

I decided to not use my non-red dot 12.3" unit... just posted it in the Classified section in case anyone following this thread might be interested in it.

Need some help. Should this quadlock adapter be easy to connect? Should slide in and lock nice and easy? For some reason I can't get this to connect fully. Made sure the lever is fully up but it will not slide in and lock, didn't want to force it either for fear of bending pins, etc . Is there a trick for this? Connecting back to factory radio is no problem so I'm suspecting an issue with the quadlock power adapter for the aftermarket radio. The seller claims the issue is not their part and my installation. Ive attached a pic of it trying to connect.

 

If I remember correctly, it doesn’t slide all the way in. The last part is done by means of closing the latch. As you close it, that will pull the remainder of the plug in, if that makes sense.

 

They have have PCM 4.0 quad lock version......this may be the problem........is this from DAINAV ? Needs pics like @Santirx mentioned.

 

After some wiggling and force it finally seated. Not the greatest fit but I guess it will have to do. I don't see any connection for this to the upgraded radio, is this ok or the radio is missing it? Also, can I used the factory sat radio connection for the 4G input? Thanks!

 

There are some new 12.3" Android units with a Qualcomm CPU and slightly different vent appearance showing up on Aliexpress now. Two advantages:
1. They are cheaper - selling for about $700 shipped
2. They have a version for PCM 4.0 available. These are labeled "B" model while PCM 3.1 is the "A" model.

The trim and airflow rerouting looks similar to the Dainav unit. The Qualcomm CPU is 8-core with 8GB RAM and 128GB flash running Android 13. Hard to find info on this CPU but I think it has similar performance to the UIS7862 used in the Dainav.

Another Vendor like DAINAV.......with terrible reviews...... steer clear......
