Review on Double Stereo Bluetooth Support Control by Dee Holt

I gave this product three stars because it was cheap and I wasn't expecting much. Perhaps this should be considered a tutorial. The first problem is that the instructions were rudimentary and the entrances and exits were difficult to identify. For example, I wasn't clear on the difference between a brake light input and a parking brake input. Little did I know there was an input for the parking brake. The device outputs sound at speaker level. After purchasing the unit, I found that my truck had a separate power amplifier. Gotta turn the volume down, just two. The buyer should inquire whether it is a power amplifier. Revain has solutions that allow you to reduce the output signal to line level. I was disappointed that the phone app had to be downloaded to my phone in order to mirror the screen. Given the firmware programming, I really didn't want to put their app on my phone. Bluetooth gives me sound from my phone and I don't need to mirror my phone. It would be nice to show my phone's navigation, but I can get by without it. The device has a number of functions. The device always turns on when the loader is started. I would prefer it to stay off when the ignition is turned off. The description of the inputs is rudimentary. There are video and audio inputs on the back, but how they work is unclear. Set the device to AUX to use them? There is an AUX input on the front. does he have a video Of course I don't know. I'm assuming the device will mute when the truck backs up, but I'd rather not. Playback from memory card or USB stick works well. When you click on a movie, the device finds the video files. If you click on the music, the audio will be found. Is there a file explorer better than many tape recorders? If you set the device to "random", it will find files regardless of the file structure. The "Play in order" icon and the "Repeat" icon appear upside down. The FM radio works well, although my antenna is so bad I can't be sure it will meet the requirements. I don't like the UI, I keep saving when I don't want to, or I press the wrong key. I assume the nature of the touchscreen. The camera failed after a few days. I didn't expect it to last. I already had a backup camera so I wasn't worried.
