"Great Device and works great with IPhone 3GS"4.5 starson by cnardi
Pros: I was looking more for an IPHONE fm transmitter for music purposes and not for making phone calls. Not only is it easy to set up, the music sounds great and with My XM Radio app I am able to ditch one of my radios and save some money.
Cons: If i am standing to close to the car when my phone rings it wil atomatically switch to the T501 and can make calls confusing.
Summary: Best transmitter I have used with any IPod device (and I have had many)
Sound is great, its easy to use and I do not have to keep something smashed into my ear for safe driving. Highly recommended!!!!!!!!
