Customer Reviews of Soundfly BT Ultimate Bluetooth Car Fm Transmitter WMA/MP3 Player for SD Card, USB Stick
This product is meant more for the iPhone. I bought it for use with an Android and the FM transmitter part works great, links up to bluetooth easily but it does not operate as indicated with being able to switch music tracks and folders. Very little tech support on their webpage or elsewhere on the Net. Still very pleased with it though.
