Review on 🔌 TUNAI Firefly Chat LDAC Bluetooth Adapter - HiFi Wireless Bluetooth 5.0 Receiver for Car/ Home Stereo with USB DAC 3.5mm AUX - Music Streaming & Hands-Free Calls - Auto On, No Charging Needed (Black) by Lild Zimmerly

My Car: 2011 BMW 328i xDrive Sedan. I have an audio head labeled BMW Professional. These are junior systems. 6 speakers and 2 subs. No Tweeters Above the Side Mirrors Of course, you can't stream music from your phone via Bluetooth in a 2011 328i xDrive sedan, but you can use your phone. That annoyed me for a while. I've learned what to do to get what I need with my music and streaming. As you may know, the 2011 328i sedan has the Aux-In and USB jacks side by side on the center console. I decided to connect to the Firefly chat. This item is powered by a USB port to control a Bluetooth transmitter. The other connector goes to the vehicle's auxiliary connector. Now my phone is broadcasting to the car radio. I can control my phone for GPS, Google Assistant, etc. The output of the device powering the Aux port is high. My sound system is louder than with a radio, USB MP3 and/or CD player. Subwoofers really sing now. Here's a big surprise. So while my phone is connected to the Fire Fly chat via Bluetooth, it is also connected to the car phone systems. So all the audio comes in from the phone, but calls also come in through the BMW Bluetooth system. The phone stops the music while the car receives a call. It's really awesome. I was concerned that the call would go through the phone's mic, but since it's going through the car, the car's mic retains the same call quality as it did when I wasn't having Fire Fly chat. I can also use the answer and end buttons on the steering wheel. Worth $40.00 in total.
