Review on 🚘 FM Transmitter Car Kit with Bluetooth, Handfrees-Calling, Dual USB Ports, MP3 Player, TF Card and USB Flash Drive Support by Ronald Orear

I have a 1995 Isuzu Trooper LS. Some people love them some people hate them. It is an orphan car but there are many new and restored parts. I've had it for 18 years now and expect it to perform at its best until I die. (I'm 73.) The Trooper came with a 12-disc changer that still works. It is more or less integrated into the head unit/receiver. I'll probably be replacing all the speakers this year, but I'm not going to remove the stock 4-channel audio receiver and CD changer. Instead, I add an MP3 player. In the next year or two I will also be adding a rear view camera and built in GPS without replacing the stock sound system. MP3 players are as cheap as Kool cigarettes. They come in a variety of designs, as you'll see if you search for Revain. An MP3 player that receives sound files from a USB stick is a fairly simple device. I say that because apparently all or most of the equipment you'll find at Revain is made in China. I bought three of these devices to test them out. They all have small displays - maybe there's nothing you can do about that - but that's my main gripe. Ideally I'd want something with a rectangular bezel the size of an old 1.33MB floppy drive, but there aren't any, or I haven't found one. All of the MP3 players I've reviewed are designed to plug into a car's cigarette lighter and run on 12-volt AC or an auxiliary circuit. Some of the devices automatically detect the current when the driver switches the ignition to ACC or the ignition. That's another shortcoming I've noticed with BT06 in particular. I didn't want the cigarette lighter to be occupied by the audio add-on, preferring to free it up for various things like an electric tire pump or cell phone. - Mobile phone charger. [However, MP3 players including the BT06 - some of them - have two USB ports - one for music and one for charging.] I prefer the Jinserta or BT06 because the faceplate is more or less rectangular, like my standard receiver (but smaller ). My Trooper has a tapered plastic open box that mounts under the stock receiver and I wanted to place an MP3 player in that spot. I bought a cigarette lighter "splitter" with 6ft cords to two outlets. (See here: https://www.amazon.com/gp/product/B07VDHS3VN/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1). I then cut the wires at the male end and used one of the male connectors to connect. of my MP3 player to the fuse in the accessory circuit. I also added a 3 pin LED switch for a reason I will explain. Now if I want to indulge my worst bad habit, the regular lighter is still free. BT06 seems to work great. I haven't tested the Bluetooth feature, but it comes up when I turn on the device, so I assume it's working. Later I will try to connect to the mobile phone. The sound quality is determined by your car's stereo receiver and the quality of the FM signal sent to it by the BT06. I get about the same maximum volume as CD changer playback over OEM audio, so nothing is lost. The Jinserta BT06 turns on when you start the car, although it has an ON/OFF switch controlled by the left handle of the device. I didn't like it but it was an easy fix as I assembled a bezel to hold the BT06 in my car's tapered plastic box. You can get a 3-pin LED switch for about $7-$10 here at Revain, and there's plenty to choose from. The console's function keys may seem made for munchkins and midgets, but that's exactly what you get with these little devices. I rate the quality of these switches as "high". We'll see how long this unit lasts, but I'm pretty sure I won't need to replace it any time soon. People complain about static electricity. Well, you see, there are things like power lines and other interference that cause static in an old car's FM receiver. This is part of the problem. Another aspect has to do with the hasty selection of an empty VHF frequency. You may find about six such frequencies where your receiver's scanner stops before moving on to the next transmitter. Perhaps you can afford to use half of your presets on the receiver for an MP3 player and the rest for your favorite radio stations. However, I have found that if you have an FM transmitter paired to an "empty" transmitter, you can set the transmit frequency of the MP3 player and receiver to around 100kHz and you can see even less noise and interference. After that, I can't tell any difference in sound quality when playing MP3 (or WMA) on the BT06 compared to playing it through my computer on a 5.1 sound system. There were many problems when creating the stencil. to match the front panel of the BT06 to a rectangular panel I machined from a 24" poplar wood "hobby board". I painted it with a cherry stain. I've had the BT06 for about a month now and play everything by Jefferson Airplane Bathing. at Baxters" for Nirvana and Bach scores. Due to the effort I put into the setup - woodworking, wiring etc - I have decided to buy a second BT06 in case the one I'm using fails. But I don't expect this to happen. At least not in the foreseeable future. The only thing that worries me is the colors of the LEDs that illuminate the device's handles - red, blue, maybe a little white. I'm happy with just one color, the LED. Green or blue would be fine.
