・ I purchased this about a year ago intending to install it in a second car, but I ended up storing it without installing it. ・ Recently, I confirmed its operation by connecting the power supply, antenna, speakers, etc., on a desk. Ultimately, I decided to install a navigation system, so this became unnecessary. ・ The Bluetooth function also works fine; if your smartphone or tablet has Bluetooth, you can wirelessly connect and play music or YouTube audio. ・ The two USB ports are for charging on one side and for retrieving music data from a USB memory stick on the other. ・ The illumination color can be set to random flashing or your preferred single color, allowing you to customize it to your car or your mood. ・ This is a foreign product with a DC12V specification. ・ The product model number is HE-1006 ?. ・ Functions: Bluetooth 5.0 / MP3 / FM Radio / AUX / USB ⇒ Operation confirmed ・ The amplifier is 4-channel, 60W output. ・ All original boxes and accessories are included. ・ Due to the nature of the product, please understand that it is sold as-is (no returns, no refunds, no exchanges). [Reason for Sale] ・ The LED bar at the bottom of the front panel would flash (normal) in the illumination mode, and the brightness was too high and dazzling even in single-color mode, so I asked a specialist to remove the LEDs. (The part in the last image) Therefore, the LED group at the bottom of the panel will not light up or flash. ・ The FM radio frequency is for overseas specifications (87.5-108MHz). ・ There is no AM radio or road information channel viewing function.
