Review on Ultimate Android Multimedia Navigation Autoradio with Bluetooth Connectivity by Billy Mariner

Cons: The biggest and most serious problem is the horrendously high latency for most applications. I mean 10 plus seconds between button presses. The cards are basically useless and that's 99% the reason I bought these. Here's a list of all the other issues I've had: apps keep freezing, touchscreen and UI is clunky and doesn't work smoothly, Google Play can't download apps or update existing apps, everything is horribly translated into English, setup for settings requires a Password you can not change, factory settings are in a strange order and sometimes in Chinese or unreadable English, does not support Bluetooth Internet data transmission, which means that you may have to configure the hotspot every time you restart I can't iPhone 6s or Connect Pixel 5 for screen mirroring, update required via SD image, not only update via web, amp trigger outputs 5v instead of 12v which doesn't drive my amps and can't be changed, didn't with my steering wheel controls works no matter what wiring i tried, ogre a huge sh merz in the back to install properly, the user manual has no device connection diagram, the installation instructions are illegible, the sound quality for Bluetooth calls is terrible and the echo cancellation does not work, the delay of more than 5 seconds for voice calls makes talking to someone quite annoying , sometimes just plays music from my phone without opening the app, requires an app to play music from my phone via bluetooth, doesn't just work like any other device. Pros: The wires at the connectors were clearly labeled and pre-stripped, making installation fairly easy. Conclusion: DO NOT BUY. It's slower than most smartphones. This is slower than most Windows Vista computers. Possibly one of the slowest devices I've seen in this price range. It's not $140, it's not even $20. They couldn't pay me to keep using this device. 0/10 recommend, 10/10 sorry.
