• Smart technology circuit architecture provides precision voltage and resistor regulation specific to the Blackberry 8300 8310 8320 8330. Protects the internal battery longevity by modulating the charge in a safe and efficient manner.
• Transmitters emit a powerful FM signal that is the maximum allowed by FCC regulation. Advanced signal isolation provides crystal clear sound quality.
• Full FM frequency spectrum is available and is user selectable in 0.1MHz increments from 88.1 to 107.9 MHz. Advanced Digital PLL sound coding maintains stable and high quality sound.
• Generous LED screen clearly displays current frequency setting. Transmitter frequency continues to be locked in even when vehicle power is cut.
• Non-coiled cable design allows for easy routing around your vehicle trim for a more professional look. Durable construction is built to last.

This is a handy device. Use it to keep your phone's battery charged or use it to transmit audio from the phone's MP3 player or radio app through an FM channel on your car's FM receiver.

I have three complaints:

1. Sometimes the signal transmitted by the Gomadic device is just not strong enough to eliminate all hiss in the radio's output. You have to try different radio frequencies and even move the phone around a bit.

2. Because the controls for changing the frequency are part of the same unit as the power plug, viewing the frequency or changing the frequency can be cumbersome.

3. The price is a bit too high. I recently purchased an equivalent device for the iPhone for about five dollars.

This is an amazing FM transmitter. Of course I was leery since I've heard so many bad things about transmitters, but decided to give it a try before buying a new stereo with an audio jack. This works GREAT. Even my skeptical boyfriend was amazed. It even works for me when changing States while driving.. it was working great the whole way and I was surprised that the stations were all "dead" while driving. Once I unplugged it, I realized it wasn't a dead station, but it was still transmitting through a strong radio signal! Please give this a try if you're questioning an FM transmitter. This is GREAT for using Pandora through my phone, and saved me hundreds of dollars!
