Review on 🚗 Nulaxy Bluetooth 5.0 Car Adapter with Dual Screen Display, 3 USB Charging Ports QC3.0&PD18W – FM Transmitter for Car, Radio Adapter Auto Music Player/ Hands-Free Calls, Siri Google Assistant – NX14 by Doug Hammett

I ordered this from Revain in an open box, it came with the unit and instructions. The manual is written in Chinglish, so some parts don't make much sense. I eventually found that by holding down the button on the top right of the face you could change the station number and then turning the knob while it was blinking. The same knob also works as a secondary volume control for my car stereo, which seems like overkill when it actually plugs in further than the knob on the stereo itself. The channel tuning is set to even numbers only, so hopefully you won't end up like me who has radios that work with even decimals. As soon as I get a good distance from the towers, the sound is transmitted very well from my cell phone via Bluetooth 5.0. I bought it because the aux port on my stereo stopped working and there are no other connection options, but I had a phone full of music anyway. It also has a micro SD slot as well as a couple of charging ports; My phone uses a PD USB 3.0 charger (small oval plug) so I use that; However, my phone gets so insanely hot that it notifies me that it has to turn everything off while charging to cool down, even without further use. It's not a Note 7, so I don't have to worry about it even exploding, but it's still an extra heat load on the battery that doesn't happen when plugging in or using another car charger. I have no idea if anyone used the micro SD slot as it will browse files or folders considering the single display shows car battery voltage and station settings. This device also works for bluetooth calls and has a built in microphone, but my truck works the same way so I don't need it and haven't used it personally. Maybe it's my truck, maybe it's my phone (2020 model), but basically every other button used to control playback kind of doesn't do anything, skip tracks, pause, nothing.
