In Car 4-in-1 WMA/MP3 Wireless Modulator/FM transmitter for SD Card, USB Pen (Flash) drive and MP3 players (like iPod). Black with Remote Control.

This gadget works pretty good, but is not perfect!

Pros:
>Has a lot of frequencies to choose from
>Good FM Stereo sound & and is pretty good most of the time (sometimes there is some interference)
>Very compact
>Actually worked with my 1GB SD card
>Comes with a remote (although you can easily operate the buttons on the unit by hand)
>Remembers set frequency and last song played if you remove it from car (or turn power to unit off)
>Great bargain for the technology

Cons:
>The display shows the frequency, track #, name of song; but it is so tiny you cannot possibly read it while driving!
>The major flaw is that you cannot jump from one folder to next, you can only advance song by song (but I suppose that's ok if you have all your favorite songs in the SD card, or plug in an external MP3 player in the jack provided)
>Another little glitch is that there is no OFF button on the device. My car's power outlet is always on. So I put the MP3 device on PAUSE when I stop listening (otherwise the songs will continue being processed by the MP3 player)

Great buy. I usually use different vehicles so i decided to get this so i can carry my kinda music around. No longer have to worry about non mp3 car stereos. Quality is very good (i was surprised) particularly using the mini jacks. The remote is just great. Can control volume, frequency, even EQ. Only feature missing is a power button. Pulling this thing in and out is getting really old.
