Dang. Well that tears it. Thanks, Recursion.
Guess it's back to the drawing board. So what I'm looking for is a convenient holder that won't leave any marks or glue on the dash, compatible with a good transmitter, perhaps a transmitter/charger combo...
like this, maybe.
With the Kensington, when you say RCA, do you mean a singular 3.5mm plug?
Perhaps I should start a whole new thread inquiring generally about what kind of charging/transmitting set-up people have with their TP2.
