Let us know how it works for you. I have read reports that it send out an annoying beep every 40 seconds or so. That is the only reason that I haven't bought one yet.
I actually bought and currently am using one of these.
They are all the same no matter where you get it from. It's called the ALLKIT for the iPhone made by one of the many chinese vendors
like the one found
here
Soon as I got it I took it out of the package plugged it in and I had no power. Opened it up and it had a blown fuse. The next day I took a trip to Radio Shack to pick up a 5 pack of fuses.
Installed a new fuse and plugged it in. It immediatley blew again. Tried one more and it blew again. There was a short somewhere. E-mailed the store where I got it from. No response.
Well after two days with no response I figured. Oh Well it was only $28. So I couldn't help myself and took it apart. It turns out that there are two wires connected to the 12 volt power portion of the unit. My unit was turned a little too tight and it partially broke the solder making it have contact with the ground shorting it out. On top of that the wire that they use is poor quality so the twisting of the two wires rubbed the away some of the rubber coating on the power wire.
So after a sloppy re-soldering job and a retapping of the exposed wire. I got it all back together again. Put in a brand new fuse and voila. Unit was operational.
So after using it. I can say that if your going to use it for Hands free forget about hearing the other person on the other line unless you turn it up all the way and roll all the windows up. You can barely hear any of the system sounds as well.
As for it's main function that I bought it for. Pandora, AOL radio and iPod all come through it loud and crystal clear. I love it. It sounds great. The transmitter works just as good as some of the other namebrand units my friends have. I also can confirm that it does have an annoying beep but you can't hear it if your using a Music application. Over the Hands free..you can hear it.
One last thing, I'm using a Griffin Elan form case and it barely fits in this unit with it expanded to it widest setting. I also own an Agent 18 case and it doesn't fit.
I finally got an e-mail back and an offer to replace my faulty unit. But my impaitence got the best of me. Too late.
Overall I'd say you get what you pay for. but it works.
