There is, can be done for a couple of hundred dollars, but there's a catch. In the Name of safety, the FAA, says that this kind of technology has to be certified, a process costing millions upon millions, thereby driving the cost for the same piece of tech to cost upwards of 20k a unit for a certified aircraft. Meanwhile they say it's perfectly okay for any joe blow with an experimental aircraft to install the exact same piece of equipment without the FAA stamp of approval for pennies on the dollar. 

I will say, recently the FAA has begun to use some common sense on this matter, allowing some stuff not previously certified to be used in certified aircraft.
