As one previous reviewer noted, there is no on/off switch on the unit which would be helpful vs. having to physically remove it from the outlet to power it down. And as a word of caution, depending on the location of your power source in your car, a smaller unit might be more practical – in one of my vehicles the shifter is in close proximity to the outlet and I have to be cautious not to bang it into my ipod when putting the car in park. This isn’t really a problem with the unit itself as much as a design conflict but is something to keep in mind as you’re considering which docking station might be right for you.

Overall I’m extremely satisfied with the unit however. I wanted something that would serve as a mounting dock, charging station and FM transmitter at a reasonable price and this unit ably fills the bill.

Pros:

- The mount is sturdy and holds my iphone 3g in place so I can see and touch it without reaching.
- The built in charger keeps my phone fully charged for when I get to work or back home
- FM Transmitter works VERY well when I can find a clear station
- Hands free option is a nice bonus. Received calls are routed through the speaker system and the iphone picks up my voice.

CONS:
- Finding a clear station can be dificult in a high density area.
- No On/Off button

First it is very easy to use. Find an empty channel on your stereo and dial it in on the top of the holder. That’s it! I’ve gotten a clear and strong signal each time. One time when I turned off my ipod there was a station on that channel yet the Advanced system had remained clear.

My only negative about it is that it doesn’t shut off the ipod when you shut off the car. I end up removing the entire system when I leave the car or the ipod will keep running or have to turn off the ipod. In a way this is not a bad idea anyway. Hate to tempt someone who looks in the car and might see it.
