Review on 🚗 Aigoss Bluetooth Car Stereo - 4x60W Car Audio FM Radio - MP3 Player - USB/SD/AUX - Hands-Free Calling - Wireless Remote Control by Anthony Hobby

The sound is normal. The remote is completely useless and needs to be less than an inch away and pointing directly at the front of the receiver to work. If you can actually get the remote to register a button press. Installation was fairly easy, but with some interesting caveats about consistent and switchable power. Dyno test OK, vehicle OK, ground loop added, current reversed, wiring checked again, all OK, reverse current disconnected, operated for 2 ignition cycles. Power switched back to normal, unit unplugged, tested on stand. Repeated process on the bench was able to recreate the situation. I unhooked everything, put it back in the car normally, it works. This will most likely not affect anyone who only installs the head unit once. However, for the price it should work well if you do NOT need a remote control (e.g. for a hidden system).
