Here's my gps instalation for my gps and backup cam. I'ved try to have it install by the dealer and they charge me around 1500$ for an interface for the uconnect 4.3.
i bought the magellan 5255 with the wireless backup cam and make my own mounting device for the gps.I used an old tube clamp i found in my stuff ans a piece of velcro.
Not in the uconect but i think it's looking great.
