※ This is a defective product. The functions work without problems, but some screws are missing, so they may come loose. (See image) I've been using it for several months after losing the screws, and they haven't come loose during use, but since they are not fixed, those who are concerned may need to adjust or fix them. Wired connection is not possible as there are no wires. The last image was taken from the product page where I purchased it, but some functions may not be supported if the product has been renewed. I will change the information if I find the screws. In that case, please understand that the price may be increased.

You can quickly charge your battery without worrying about the battery level, even when using apps that consume a lot of power, such as Google Maps and YouTube videos. ✅【 Easy 1-minute setup 】 The specifications allow even those who are new to FM devices to connect in just 1 minute. Furthermore, the setting is adjusted to automatically connect when the engine is turned on from the second time onwards. ✅【 Improved sound quality | More comfortable music playback 】 After many years of improvement, the slight difference in volume that occurs between AUX connection and Bluetooth connection has finally been greatly improved. It achieves music playback at almost the same volume as wired connection (AUX connection) even when connected via Bluetooth.
