I installed a Chinese car stereo/DVD/GPS in my Honda Civic in 2012, and was satisfied with the purchase. It was powered by WinCE, which is an operating system I do NOT recommend. The Android OS is supported by Android, and there is a huge amount of 3rd party software. By comparison, Microsoft has largely terminated support for WinCE, they've abandoned further development in that arena, and there are no 3rd party applications available.

My advice would be to purchase the latest version of Android available, and the most capable processor; that would be the largest number of cores, and the highest clock speed. Also get the largest available RAM and ROM configurations. The reason for getting the best hardware configuration available is to minimize start up lag, and improve responsiveness with the latest OS. With the best hardware, the Chinese units are very responsive. Even less capable hardware platforms respond well, but take longer to start up. There are a number of YouTube videos regarding various peoples' experience with Chinese Head Units, and in general most people are very satisfied.

Be aware that many units have identical front panels, but are very different inside. One way of determining whether you're getting the same hardware is to look at the rear of the unit (if they show a photo). Different hardware will almost always have a different plug layout on the back. If the rear of the deck is identical, there's a good chance that the decks you're comparing have identical hardware. When searching for your unit on a website like AliExpress, include your automobile name (Focus, Alantra, Civic) in the search term. This will bring up units that will fit your vehicle. Because dash layouts change over time, search results will include terms like 'Focus 2012 2017' which tells you that the particular unit will fit all Ford Focus vehicles between the years specified. Don't put the specific year of your vehicle in as a search term; it will just muddle the results.

Chinese head units often offer features that are not available on locally sold units. For example, my unit allowed me to stick any audio CD into the reader, and it would copy it at high speed into memory, where it would reside forever. This kind of feature is not built in on most North American head units, due to copyright infringement laws.

I purchased a USB modem for my head unit that would allow me to surf the web over a 3G phone network. It worked well, but I would not - in most circumstances - recommend it, simply because entering search terms on a vertical screen is physically cumbersome. I found it much simpler to use my handheld phone ( a Note 4 ). However, if you want to stream YouTube videos, streaming them on a larger screen - or to the back seat, by means of a video out terminal on virtually all Chinese head units - might prove superior to watching them on a small phone screen.

One very good reason for having a USB modem is if you wish to go on a lengthy road trip using google maps. While it is technically possible to download static map coverage and store it in the unit, in my experience Google limits the number of map sections you can download to a strip about 200 miles long. Also, those strips cease to work within 2 weeks, and must be refreshed. While I like Google navigation, the constant connection required can be problematic, particularly if you're visiting a foreign country (Canadian in the US, US citizen in Canada, either nationality in Mexico) where your regular data plan is not supported. Under those circumstances, Google maps can get real pricey. A better solution would be to purchase GPS software, and update the maps regularly. I have used Igo 8, and I found it to be excellent mapping software, with a number of extra features (speed camera locations, exceeding the local speed limit warnings, local speed limit display) that I found very useful. There are other good software choices as well.

Most units support many dozens of languages; my unit was supplied with English, but I could have changed it to any language I wanted. I also was able to specify that when my unit turned on, it displayed the Honda logo, which added to the 'factory install' appearance. Again, you can choose from dozens of company logos.

Most installs are very straightforward, and can be completed by an amateur in an afternoon. I'd recommend watching some YouTube videos first, in order to determine if this is a task you wish to take on. In my current install, I have to run an antenna line from the trunk to the head unit in the dash, as the trunk is where Mercedes put their amplifier/receiver. That's unusual, but watching a few videos first will help you determine the difficulty level. In most cases, it's very simple. Custom wiring harnesses are usually supplied with the unit, as are plastic shells and trim pieces that allow it to merge seamlessly into the dash and look like a factory install. My Civic was supplied with a huge plastic dash panel, several times the size of the unit. But it clipped seamlessly into place, and made the unit look like it came from the factory that way.

In general, Chinese auto head units offer excellent value; they perform as well or better than locally available units. My sister spent $1,500 for a top of the line Clarion, and was so disgusted with it she gave it away, after several angry verbal exchanges with the shop that sold it to her. I tried working with it as well, and found it to be so buggy as to be impossible to use. By comparison, the $300 I spent bought me an excellent, well performing unit. I'm currently purchasing another one for my Mercedes, which I guess speaks to my confidence regarding their quality and value.
