    Great radio

    Great radio
    I've been using this radio for a while now and so far I love it. The sounds not bad especially after you mess with the eq settings. You can change the brightness relatively easily as well. The speakers it comes with aren't too bad and I'll probably keep them as a backup in case my current ones go out. I mostly use Bluetooth and so far no issues with the display going out or sounds dropping. Great radio.Additional information 5/15/2018: My screen went blank once and I contacted customer support. They were quick and informative also giving me a PDF describing exactly what they were telling me so I could see visually. If you have screen issues all you have to do is hit the tiny reset button with a thin object. That fixed mine right up.

    This is a great little system with good sound. The 2 speaker with deck sounds really good in my side by side. Did a little custom work and looks great! Was easy to hook up Bluetooth.
