I have a 01 Dodge Ram sport that currently has an aftermarket JVC cd reciever in it. I want to upgrade it to something with ipod control and possibly, bluetooth. Is the wiring harness universal, or would it only be compatable with another JVC head unit? I dont mind wiring in another harness, but it would make it so much easier just to plug and play the new unit. While we're at it, any reccomendations for a sub $300 head unit with ipod control and bluetooth?
