Query: ICarPlay No Good

I purchased the ICarPlay Wireless from CazyOnDigital. The first unit did not work at all. When I plugged it into my iPod, I got a message that the unit needed to be charged. My iPod was fully charged. The unit would not allow me to select any songs and did not play through my FM radio as it was advertised to do. I returned it and after some period of time, I just received the replacement unit today. I attempted to use it and still have problems. it will play one song then hangs up my iPod. It simply freezes. If I unplug the ICarPlay unit, the iPod continues to work properly. It seems like the wiring in the iCarplay unit is wrong. Therefore, I would be very careful in buying this unit.
