Fm transmitter for iphone 5

[toomanyphones]

I am looking for a fm transmitter with lightening plug. My 05 Vette has no way to interface the iPhone with the radio/GPS except through the FM radio. It is a poor solution, but it is my best choice.

I think those are just starting to trickle out, but I've been good with my old Griffin FM Transmitter/Charger paired with a 30 pin to Lightning adapter. Works fine and saved a few bucks.
