Question: What is the distance range of FM transmitter?
Document: I needed another FM radio transmitter for my car as I had a highly rated one in the past and it broke.This one doesn't look as nice as the picture shows but works as intended.
Bought this item thinking that it'll be much better than the cheaper alternatives available considering the price of the FM Transmitter but some of the buttons were not functional and were loose. The Auxilliary cable is not working properly.
Now it's great. Huge difference.3. Music Scroll:  The buttons in the front around the volume knob allow you to easily scroll through the music on the device that is plugged in. It makes finding songs much easier.4. Lights and Station Control:  My old FM Transmitter didn't have lights so it was difficult to use at night without the car's dome light.
Load music onto a device such as a phone, mp3player or a USB Flash Drive. Plug the FM Transmitter into the car's cigarette lighter. Set the car stereo to the same station as the FM Transmitter display. Plug your device into the FM Transmitter (there are two plug ins; a usb port and a headphone jack). Adjust volume on car stereo AND on FM Transmitter.
Such as folder skip.- Picking the frequency is important and I am surprised how clear it is when I got the right frequency. It will vary so you have to scroll through all the frequencies in your city to get the best one. It still can pick up interference like any FM tuner.Cons:- This product has a size limitation on the SD card. It will not read over 16 GB.- I am not aware there is a size limitation on USB but I believe it also has one.
This was an upgrade for me from the $3 one and it's a huge improvement.1. Ability to Open Files:  Previously, I had to save individual mp3 files to my device (phone, mp3 player or flashdrive) which took time because all my music is stored in folders by category or album. So this features saves a lot of time.2. Volume:  This device has a volume knob which greatly improves the sound quality on the car speakers.
This is a good product.
This device plays much better than the previous one I purchased about two years ago. Buttons are easy to see and push. The only downside is the lack of a good grip to plug the device into the car socket. It is too slippery and you can't press down from the top as you will be pressing down on the control buttons.
The reviews are true. I have been using this for a couple weeks now. It's ok, but...-It is cheaply made and doesn't offer much adjustment from the swivel.
Pretty good , a lot of bass and too bad the it didn't work with my iPhone as a usb but it's ok
Answer: It's not good clarity is horrible! High static while driving, tried so many different stations.
