The board generally works well, the sound is good, there is enough power with only 12V DC. Unlike the other browser, I thought the USB/SD player functions worked fine. I couldn't get BT to work as an audio device. I was able to see the radio but didn't register on any of my phones/computers with downloaded audio services. Forget FM radio, I didn't waste time installing any antenna and all that got by without it was the usual signal noise. It could work better with some effort, but I didn't care. I took off a star because I really wanted to use BT along with other features.
