Frequently asked questions:

Is this product plug and play? Do I need to program or code my Audi? Do I need to buy external GPS antenna? Can I still check the car info as the OEM screen?
Answer: Yes, it is totally plug and play, it has the same plugs and harness as original Audi system. You do not need to program your car when installation. All necessary accessories are included in the package. You do not need to buy anything else to make it work. You can still check the original Audi car info as before.

How do I switch the new Android system to the original Audi interface?
Answer: Please tap “Car-info” icon on the home screen to switch to original Audi interface.

How do I switch the original Audi interface to new Android system?
Answer: Please tap the screen.

Why it shows “No signal” when tap “Car-info” to switch back to original Audi interface?
Answer: Please check the CAR-LVDS port. Make sure you connect the LVDS plug (removed from the OEM screen) to the new screen.





Why there is no audio from new Android system? 

1. Please press MEDIA button on the raido panel and check audio source options.Make sure the External Audio input(AUX) is activated.


Note if your car has the AMI option instead of AUX, then you need to plug the Audi AMI-AUX cord(this cord is sold separately) to AMI port in glove box on passenger side.After plug this cord, the AMI will change to AUX on the screen.

2. Then tap the screen to Android screen. You should be able to hear sound.

Where should I mount the main metal box? The original LVDS cord is too short to mount it in the glove box?

Please take apart the glove box on passenger side and there is a hole allows you to put the metal box hide behind the screen. Then the LVDS cord is long enough.

    After a lot of frustration and wasted money, I finally had an aftermarket navigation system/rearview camera/CarPlay, and much, much more. I have a 2012 A4 (B8), and I looked and I looked but couldn't find a third party system that would give me at least a rearview camera and - ideally - a navigation system. As most of you know, the big issue with this is the car's MMI system, which essentially controls much of the cars interior operations. I eventually found The system is - so far - awesome! I've had it over a week, and - while there isn't seamless integration, it provides more than I'd expected I can get. I'm not going to bother listing the highlights, but I recommend that you go to the site to check it out. I'm not going to lie to you. There were some significant and expensive hurdles along the way before I got the system just right. Most of these issues came in the form of installation. I went to one car stereo installation store, and they said that they could probably install the unit, but they couldn't promise how well it would work. The store is Audio Toyz in Mission Viejo, CA. I should've hired them right there because of their honesty. Instead, I went to another retailer, West Coast Auto Sound (also in Mission Viejo) because they said they could do it in two hours for $200. I dropped the car off the next day. It took them almost seven hours to "complete" the job. When I took the delivery of the car, they handed me my keys, told me that the job was done, but they couldn't tell me how to use all of the functions. That was fine with me because I could always read the manual. It didn't work. The rearview camera did its job about 20% of the time while CarPlay didn't work at all. Also, the third party nav system wouldn't play music while the navigation system was in use. So, I had to choose to get directions or listen to music. I went to the shop the next day to talk to them about this. I walked the guy who installed it through the problems I experienced. All he said was, "It's plug-and-play. It's plug and play." Literally, other than "hello" and "goodbye," he didn't say anything else. So, I took my car to Auto Toyz. They took over 3 three hours to undo and fix what West Coast Auto Sound did, and they only charged me for two hours. The system worked beautifully! The guys there rock! They were knowledgable, professional, nice, and effective. Super-effective. I love the system! Sure, there are some less than ideal things like having to plug-in my iPhone inside the glove compartment every time I get into the car. I end-up forgetting it's in there, and I have to go outside to my car multiple times to retrieve it. Also, I have to swipe the screen twice and press an icon on the third page to get the CarPlay screen up, but this is nit-picking. At the end of the day, I love the system! From what I've seen on the market, there really isn't any other product that competes with this. Fortunately, the one that is available is a really great solution.

    The unit itself is good. the instructions that were sent with the unit needs to be updated, its missing certain steps. The customer service is outstanding. emails on setup were replied within minutes..... very impressive for this company.

    This unit is amazing. I'm telling you it does everything you need it to do and is perfect for my sons Audi A4 2011. All the features are as explained and easy to use. I would recommend this to anyone as its much cheaper than and Audi unit.
