[FYT Android Head Units] i928:
I share my 2 cents experience for android headunit.

I bought headunit($87) 4 cores, 2G RAM support zlink in 2019 for 92 ls400 I did not choose head unit support AA(Android Auto) as its price was $200+. Well, zlink did support mirror phone's image, but it is slow and buggy. I decided to run google map on the screen, but the screen froze after 15 min drive due to overheating issues. It works properly after installing cooling fan. I wanted to run Android Auto, so I spent 4.95 to purchase Headunit Reload(with sharper images on my screen), Android Auto ran great on screen with USB (with sharper images). I tried with wifi,but sometimes google map lagged due to 2.4GHZ wifi. It seems like most of headunits support 2.4GHZ. Mekede M200S/M400S/... support 5.0 GHZ wifi. My phone got very hot with wireless mode. If your headunit supports 5Ghz, you could run into other issues. 5Ghz might get interferance during rush hours in metropolitan area. I always use USB connection for AA.

I bought Mekede M200 8Core, 2GRAM specified for camry for 07 Camry because there is cheaper one facia also cover AC control buttom, but does not fit my car, and Mekede one is perfect fit and has a built-in fan. Find a proper facia fit your car can be little tricky, because seller claims it fits your car but does not. For example EKIY KK3 for LS430, its facia did not properly fit vent wheel, you have to cut it to fit, buyer has to purchase a new facia from another vendor to have perfect fit, but EKIY KK5's facia is perfect fit for LS430. Why seller use different brand facia on different model for the same car?

8 cores 2GRam works fine if you only run Android Auto, Car Scanner and HD DVR. It would be safer to get 8 cores, 4G ram.

Canbus is important part for headunit to work properly. it control AC/steering wheel control. Sellers claims it works does not mean it works properly for all models.

I am surprised not many users ask about canbus brand, canbus setting, or their canbus does not work. Users on LS430 forum ask about canbus setting to get AC work properly. Working properly means different things for different canbus brand, some mean you can adjust by using factory button, while others mean you can control on AC temperature from screen too.

If you want to add 360 camera in the future, you need to order 360IC chip with your order, so seller can install it on motherboard before shipping.

Carpuride or Lammto are good for easy to install. There are some issues too.

1. Lammto seems to lack usb port for phone connection, so you have to use wifi connection. you might run into issues mentioned earlier. If car share with other people, it will connect with the last user that connected when the people are in the same car.

2. Suction cup issues. suction cup fall off and some only last 3 months. How long does it stick on dashboard?

3. If you live in places has hot summer, the shelf life might be shorter under the heat of the sun. Some users complain it died within 1 year. Dash cam has similar issues. SD card can die quickly. I live in San Francisco bay, temperature outside can be about 70F, but under the sun, the temperature inside the car can be as high as 125F, and Dash camera temperature up to 174F. No wonder many users complained about dash cam died after few months usage.

4. It is thief's target.

Summary:

1. choose unit with built-in fan, or install external fan after purchase.

2. min req: 8 cores 4G ram.

3. order 360IC if you install 360 camera in future.

4. make sure canbus works for your car if possible. Ask seller to confirm, at least you can dispute when it does not. It will long and painful experience to dispute if unit does not work. Of course, it is easy process for Amazon buyer.

5. preferance: USB for AA.

6. choose 5.0 Ghz wifi over 2.4 Ghz if possible.

If your car has good forum support, you can ask what others buy and their experience with units.
