Review on Advanced Double Din Car Stereo: Android 10, Navigation, Carplay, DSP, Bluetooth, GPS 7 Inch Touchscreen, DAB, OBD2, 4G WiFi, DVR, USB, SD, AUX + Backup Camera by Paul Williams

Great value. Here is the installation guide. The RCA line outputs are unique in that they are pre-shared with the subwoofer output. That means the bass is off the grid and the sub only lets through low frequencies like it should. The problem is that my factory Bose system expects full range output from RCA left and right. As a result, I had no bass response. I have 2 solutions for this. one). Buy cable for 3 years. One that is a male and two female connectors to separate the auxiliary output and two that are single male and two male connectors to combine the main and auxiliary outputs into the left and right amps. 2). I also tried using the front left and right speaker wires connected to an RCA jack adapter. It actually worked great without overloading the amp's inputs. Each source has built-in volume controls so you can balance the signal between radio, AUX, BT, phone and video. In addition, there is a factory service menu that allows for more balancing and other functions. Go to Settings, Infotainment, scroll down to click About, then click the Settings icon on the right. The passcode is 8888. Please note that any changes must be saved, resulting in a hard reset of the main unit and loss of custom equalizer and balance settings. Discovering this gave me full control over my installation. Honestly, I don't miss Apple Car Play. . I can use any navigation map app with built-in navigation software. I chose Raindar because it shows a Google satellite map with real-time traffic and weather radar overlay! This requires WiFi, which I use all the time in the car. If information about the audio output equalizer and service settings were documented, I would give this device 6 stars. In the end I bought a Mercedes Bose. amp thought he was out. Waste of money for me, education for you. Enjoy
