I purchased this one.
Its basically the same, but a bit more ram, memory and layout is for auto AC. It is freak'n amazing compared to the 8.4 AN4 I had. Nothing but problems. This units is like have a PC in my truck. There are MANY, MANY of them, but what sets Rongji apart is the metal back with a fan. That is why I went with Rongji, and it keeps the OEM back up camera and EVEN improves it! The mic, well, still messing around with it. Will probably replace it with this one:
There are a few issues though, mostly petty stuff, but still thoughts. I would like to add that since I installed Nova Launcher, I do not have any more Android Auto hangups...or black screens, it is way more reliable and customizable. Also fixes the Celsius to Fahrenheit issue. Below is from my review on Amazon. However, I still HIGHLY recommend this radio and certainly its support.
A few things I have noticed.
1. I cannot figure out why on earth the OEM micro usb connection doesn't work. I have used the correct connection, but still nothing. This means that I have lost the usb, aux jack, and the sd card slot inside of my arm console. Not a show stopper, but really? Why doesn't this thing work? Its really, really simple and does show some form of laziness on the engineers side.
2. Why didn't they include a cable to connect the onboard satellite that is already on the truck? As I do know it is superior to the one that is included in the kit. Just doesn't makes sense and would have also saved them money and given the consumer a better product.
3. It doesn't always automatically start Android Auto. Well, that's not correct. It does try..but it just hangs up. Not all the time, but probably 50% of the time. All you have to do is drop down the menu and clear it. Then it connects. But why? Also, there are numerous black screens, again, clearing it solves this.
4. The stereo sound is not as good as factory. I have been playing around with it A LOT and still can't get it to sound as good as the OEM radio (Alpine speaker system). Neither do the radio stations...I also miss the subtitles on the radio stations stating what is playing and by who. Sometimes they show it....but it is very small and in white lettering...small white lettering.
5. Still cannot change the Celsius to Fahrenheit. States I have done so, but doesn't change. This can be rectified by loading a Android Auto Head Unit Launcher, such as Vivid Car Launcher, Car Launcher(Pro), AGAMA Car launcher, etc. But you shouldn't have to do this for something so simple.
6. Though there are numerous customization's you can do, making changes to the default desktops is very limited. I am already tired of looking at the females face to the music player on the home screen. I cannot change this. But I am working on this.
Here are a few pics of my AA HU. Still messing around with it, but absolutely love it! Night and day compared to MOPAR head unit, or at least the older ones.
