I'm ASSuming that you read the manual that was presented with this FM Modulator and read the section about its features (the USB slot) and which formats, and how to get it set up, etc.. I'm ASSuming you did that, right?
Of course i did!
Ill even put the steps on here for you to enjoy!!
1) Plug in the FMTD5 (fm transmitter) into your cig lighter or 12v power socket
2) Tune your radio to a desired FM frequency, then match that same frequency to the FMTD5 by using the buttons on the unit, or on the remote(see overview) HINT: Tune to a frequency with no station for best sound quality results.
3) Insert your USB Flash Drive into the USB slot on the FMTD5(see figure 1)
4)The FMTD5 will display the USB icon on the top left corner of the LCD to confirm the USB flash drive has been loaded properly (see overview)
5)Press play on the FMTD5 or remote control and being listening to your music through your car stereo. Enjoy!
The overview says this :
The scosche FMTD5 Digital FM Transmitter gives you more ways than one to listen to your favorite music through your cars FM reciever. You have the capability to listen to the audio files (mp3) from a portable USB 2.0 flash drive or you can listen to your mp3 player through the auxillary imput.
I do have a flash drive that is a 2.0, and the steps for getting it to work i do correctly. The song comes up on the display and all, the sound is tuned in fine, but nothing comes out.
