Im sure this has been beat to death a million and one times, but is there a way to connect my android phone to my factory radio? I have the RAQ 6 CD changer unit with the infinity premium sound package and no nav. I have the option for satellite radio however it is not used (I dont have any subscriptions). Ive seen adapters selling for anywhere from $50 - $150 on ebay and crutchfield but I dont know what I should be looking at. One forum said this unit HAS an aux in in the back for some VES (I think thats what its called?) system...which I dont have. What is the cheapest way to get an aux in port?

Just to be clear Im not looking for an FM tranmitter...those things have terrible sound! Im looking for an actual way to get a line in physical port for my radio.

Thanks in advace!
