I upgraded the carplay by adding carlinklife carplay module. PCM3.1 Original radio retained. The sound quality has been improved a bit, with DSP function. Original car cameras can also be used.

That seems to be a rebranded Isudar module. There are about 2 or 3 main manufacturers out there and a bunch of rebranded sellers. I had Isudar in my PCM3.1 as well, and decided to ditch it for Mr12Volt as it has better audio quality than Isudar.

But given I wanted a bigger screen, I moved to this Android unit.

BTW… all these retrofit units are also based on Android software.

There are a few threads on Isudar here and you can discuss your issues or concerns on those threads.

Looks good ! My car is apart...and I have the MOPC-1 on hand.
@pixel1987 Can you please post a picture of the accessory antenna's that came with? I need to position at least the CELL antenna, thinking in the Center speaker recess.
Did you order the FAKRA GPS adaptor cable ??? You will need that if you plan to use the OEM GPS.


Good luck

Mine came in yesterday! Everything looks great. I'm going to start install tomorrow. However I have to wait till Monday for the upgraded fiber module to come in. 😔

Looks clean. Nice!

Good thing that they took our recommendation seriously.

The new unit looks simply gorgeous! I was in touch with DaiNav to check if they could provide a MOST converter with TOSLINK input, like the one from @Santirx, but alas they can't. And that very box seems to be rarer than unicorn blood... so I gave him as feedback that the unit should have a MOST output. A lot of Aliexpress units have that. And he said that he would pass this over to the engineer.

I have also looked hard for that TOS-MOST convertor....no luck. I guess the good news is the MOPC-1 box sounded better anyway in @Santirx review. But would have been nice to try it !

Yeah, if I see that my feedback leads nowhere, I'll certainly end up getting the MOPC-1 box... or maybe replacing the stock amp with one with TOSLINK input :p

I was also tempted to ask them whether their engineering team could send me a MOST board to connect to the unit. After seeing the TOSLINK board that was sent to @Santirx, which was nicely interfaced through a connector, it makes me wonder whether it would be possible to do something similar, with the same board connector, but with the MOST output socket instead of the TOSLINK one.

Would require rework of back plane panel......dont hold you breath :)

One potential problem with integrated MOST output here is that PCM 3.1 and 4.0 use different MOST protocols, which would limit flexibility slightly from the manufacturer side. Of course if the protocol could be changed in software, that would be a non-issue. That said, I think these are mostly using generic main boards, which is why we need the external MOST converter and CANBUS boxes.

That's a good point, and I was completely unaware of it. My proposal came from the experience I have with my current unit, which I purchased back in March:

https://www.aliexpress.com/item/1005002466045563.html

This one comes with an integrated MOST port, which makes integration so much smoother and simplifies the cable management to a great degree.

I am not sure how does the unit above manage the selection of the appropriate MOST protocol, or even if it even supports correctly both protocols. For cars based on PCM 3.1, it certainly works as it should.

In either case, I reckon that the same problem would apply to external CANBUS boxes: if these boxes are able to encode the analog signal and choose dynamically the correct protocol, it should also be possible to do the same with a MOST board integrated in the headunit. That's just me guessing, though...
