Installation was relatively straight forward thanks to the reviews here on Amazon that give good tips. You need power to the Yellow Battery, and Red Accessory wire along with the Black ground wire. The radio is not the most appealing design, and while it does provide the functions it advertises, they leave a bit to be desired. First, HDMI ARC, the ONLY reason I purchased this unit seems to be really finicky, it can take 15 seconds or more for the audio to come on. For some reason, HDMI Arc is TV Audio input 2, who the heck has analog connections anymore? Sound quality isn't anything to get excited about, bordering on poor. That said, in a camper, it's adequate, but certainly nothing you'll impress guests with. Bluetooth does work, but what ever you do, don't waste your time with the App, it's garbage at best. For those that want to connect a Bluetooth speaker, this unit does not do that, it only allows play back from a Bluetooth source like your phone. Radio tuner refuses to pick up many channels the previous radio did, I can't explain it other than to assume the tuner is lower quality. Further, the depth of the radio barely fits in the wall space that we have in our travel trailer. It would fit fine if we didn't have the antenna connected, but as it is, the depth with the antenna plugged in is just about 1/2" too tight. Would love to know where to get a 90 degree extender to alleviate that problem. Unrelated to the radio, the OEM unit I replaced (Touch Radio) was screwed into the cabinet and was enormous in comparison. To cover up the hole, I opted to 3d print an adapter to mount the radio in the space and cover the open hole. It's a shame no one provides a double din radio mount with an extra large trimmable face plate. But as you can see in the photo, it looks like a professional installation.
