Hey guys,

I recently got a new Chinese head unit for my exciting Kia Picanto: "Carlaoer 4GB/64GB Android 9" unit. It wasn't exactly my choice. The seller does not respond.

The specs are:

CPU: AC8257 (A Mediatek?)

XY LINK (No idea what that is): 1.6 (Z2)

Radio: NXP6857

MCU: 0.7 (Z2).

There is very little information on the web about that chipset/units that are based on it. I only found one thread here that led to another thread in Russian, over at 4PDA, but sadly, even with google translate, I couldn't understand any of it (It does look quite informative). If anybody who reads my thread happen to own a unit like this/with those specs, I'd be more than happy to hear from you!

I have a number of issues with the unit. I'm guessing most of them are not hardware related and can be somehow fixed, perhaps the key is getting root, but I couldn't figure it out on my own (I can follow instructions pretty well, but I'm not a developer or anything like that):

1. Google Assistant: After a pretty random period of use and always after a reboot, Google assistant will cease to function, saying it's not the default assistant and will ask me to set it as such. However, when I go into settings, it's definitely set as the default assistant (The only one that exists). When I choose "None" and then choose the Google assistant again, it starts working again for a while. In addition, I'm unable to choose "Google enhanced voice recognition" (Perhaps it's just called "Google"), and can only choose "Basic Google Recognition" as the voice input of choice. Regardless, I can talk to the assistant and use "OK google", so I don't know if it's related or of it matters. The only solution I found online talked about installing the google app in a system folder (Needs root), when it doesn't come pre-installed with the ROM (It didn't in my case, I got it from the Play Store). However, I'm not sure that's the case here, as it does seem to run for a while. Well, I'm not sure about anything :p.

2. Bluetooth randomly loses connection to my phone. Tried various phones in various positions, all using android 9 & 10 and it happened with all of them. I'd be happy to provide more information, but I can't understand why is it happening.

3. RDS Station name and information: RDS text rarely appears. When it does, it takes anywhere from 45 seconds to a couple of minutes to appear. I have tried various radio apps I found here and on the web, but nothing worked. I'm guessing it's because they were incompatible with my cpu/radio processor. What can cause such odd behavior of RDS?

4. Lastly and probably the weirdest: The system arrived with a cable that is attached to a SIM holder. So far so good. It appears as SIM2 in the pinout of the relevant harness (And also in the settings). When starting the unit for the first time, I was surprised to find out that there's SIM1, which already includes a CHN-UNICOM sim... It gets weirder, as the phone shows a single IMEI number for both of the sims. Is it possible that it's something virtual that was left by the manufacturer in the testing/developments stage? Can it be that there is an actual sim inside the unit (It's not a 2nd hand or anything like that)? I couldn't find anyone who ran into something like this before.

I know these questions are a lot, and I would be grateful for solving even one of those mysteries.

I thank you in advance!

Have a great day :)

Noam.
