I do not have a bluetooth head unit and have no desire to buy a new head unit. However, I wouldn't mind losing a wire if possible. I currently use the aux in which is the disk changer slot style in the back of the head unit. Go from it to Ipod or from it to RCA/3.5 headphone.

Is there a way to go from RCA to bluetooth allowing me to stream from my phone to the head unit wirelessly? I am assuming if you can its going to be a powered conversion?

Is there a brand someone has used?
Are there marine applications I need to consider?
I'm assuming I should just stick to DC power? Should it be hardwired or could I just run to the posts under the drivers helm?

Aside from the technical side ... Who uses bluetooth? Does it work from all over the boat? Does it ever sound harsh?
