Review on 🚗 Car Bluetooth FM Transmitter, SONRU Bluetooth Adapter Music Player Kit for Vehicle, with QC3.0 USB Charging, Handsfree Call, Siri Google Assistant, SD Card/U Disk Support, 7 Color Lights/LED Voltmeter by John Bennett

The Most Powerful FM Modulator I've Ever Seen! The device is easy to use and works well. The only annoying thing is that the Bluetooth function is blocked when there is an SD card in the slot. The only way Bluetooth works is by removing the SD card from the device. Bought three, all the same. Keeping up with an SD card in a car is no easy task. I need to find a place to store it when using Bluetooth. If they built in a selector feature that lets you choose a mode on the device, they could charge more money for this thing, and that would be perfect. A strong signal reduces external static that affects sound quality, which is really nice! These devices are so powerful that in the same car with the standard head unit but with additional amplifiers, loudspeakers and a subwoofer, I have to turn down the volume on my mobile phone a little so that the bass doesn't boom. I've tried to turn down the bass to no avail, but when I turned down the volume on my phone while playing Pandora, the audio was clear and the device still played a lot of bass. The fast charge port charges my Note 9 like a factory charger. We have two trucks, two SUVs, three cars, two boats and an RV. Some of them are late models and have modern sound systems. Some of them are vintage and have some fairly old outdated radios with limited functionality but these are classic cars which we keep in pristine condition. These little FM modulators combine new technology with old technology, and they all go together perfectly! We live in a remote area with no standard radio signals. We also have many areas where there is no cellular signal. I have compiled an extensive music library installed on mini SD cards in MP3 format. Using a computer to copy one card to multiple cards, we can enjoy music wherever we are! Stick one in any lighter, even our boats, and we're good to go!
