Sony Car FM Stereo Transmitter —
this is easy to use, but loseing a signal is a rare occusion, draws power from your car battery, sound quailty is pretty good and it is cheap, not much to this, the knob turn for you to find set it where you want. Overall This product is good for it money, the only bad thing about it is the design as it looks like a gun
Also it takes time to set it where you want, do this before you drive it only takes a few sec
