Customer Reviews
Smart Box is great!
My Ottocast has been good, but this Smart Box for Car from One Car Stereo is even better. Updating the firmware was super easy, took less than 10 minutes. I saved 15% using a tech reviewer's code.
Detailed review of Wireless AA Dongle
I purchased the Wireless Android Auto Dongle a few weeks ago after doing some research on similar products. Ordering was simple on their website, and the product description was clear about compatibility. Shipping took exactly 6 days to arrive at my address in Texas, which was within the estimated window. Installation was plug-and-play; I just connected it to my car's USB port and followed the on-screen prompts for pairing with my phone, which took maybe two minutes. The connection has been stable, with no noticeable lag or dropped signals during my daily commute or longer drives. Audio quality over the wireless connection is identical to wired. I tested it with Google Maps and Spotify primarily, and both functioned flawlessly. The dongle itself is compact and doesn't take up much space. While it's a bit more expensive than some generic options I saw, the reliability and ease of use made it worth the investment for me. Firmware updates seem to be available, though I haven't needed to update mine yet.
Works great, easy install
Got the MINI Wireless CarPlay Adapter. It connected fast. Now I have wireless CarPlay. Happy with it.
Good product, minor shipping delay
I ordered the CarPlay AI Box HE PRO from One Car Stereo. The setup was pretty straightforward, and it worked well with my car's system, letting me use Android apps like Waze directly on the screen. The price felt fair for the features. My only minor gripe was that shipping took about 8 days to get to my place in Florida, which was a bit longer than I expected. Customer service was responsive when I inquired about the tracking, though. Overall, a solid purchase, just plan for a little extra time on delivery.
Nice upgrade for the car
So I grabbed the Android Auto Wireless Adapter, and it's been pretty sweet. My car finally has wireless Android Auto, which is way more convenient than always plugging in my phone. Setup was easy, didn't have to fuss with anything too much. It just works, you know? The website was easy to navigate when I was picking it out too. Glad I got it, makes my commute a bit better.
Love my new AI Box!
I just received my Cloud AI Box and I'm so happy with it! It was super easy to install, literally just plugged it in and it worked right away. Now I have YouTube and Netflix right on my car screen, which is amazing for long trips with the kids. The picture quality is clear and the sound is perfect. I will definitely be recommending One Car Stereo to all my friends who want to upgrade their car's tech. This has totally changed my driving experience for the better!

My car's a bit older, 2017 Honda CRV. How can I tell if their CarPlay box would even work with it before I buy?
I'm a student, any chance of a student discount code for these guys? Or like, a first purchase discount?
Hey, thinking about grabbing one of their CarPlay AI boxes. Anyone know how long shipping usually takes to say, Chicago?
can you actually stack discount codes on this site? trying to use a referral code and a holiday sale one.
are their carplay boxes actually legit? like, not some cheap knockoff that'll brick my car system?
