A New Vehicle! Who said anything about a new vehicle? Excuses excuses.
You could install a nice junkyard radio with an "AUX-in".
-or-
You could buy an Auxiliary audio-interface FM transmitter...available at Nordstroms, Niemen-Marcus, Macys, Target, et al
(or Walmart, for about 20 bucks)
Actually, I did buy one two years ago. A nice CAN-BUS Auxiliary Input Adapter. But the directions said I had to dismantle the entire dash of my Fusion to get at it.
It looked like too much work so I put it on my electronics shelf. I just went over to the shelf, and it is still there, collecting dust on the plastic zip lock gallon bag I put it all in.
I probably need to put it on my growing todo list.
