From what I hear car cd players and ribs don't go to well together. I am going to get one of these and see if there are any good.
(item called beamit)
It is an FM transmitter which will plug into your choice of output be it Ipod, mp3, personal CD etc. This transmits 10-30 feet to the bog standard radio/speaker set up that you have installed.
This way you can keep your ipod etc in your pocket or out of harms way and save having to buy expensive kit for the boat that may get wreaked in the elements.
Apparently they won't send direct to UK and I don't know what the legality of this is?? Anyone know before I get myself i trouble?
