I recently got a 2011 Sorento from a coworker. It has the basic Non UVO head unit, and it suffers from the random, intermittent radio power cutout. I was able to get a hold of a Navigation Infinity system head unit I would like to replace the other with. I know that the stock system doesn't have an amp or GPS antenna. What I need if the connector pinout info for both the stock unit and more importantly, the Nav unit (96560-1u000ca). I intend to put in an amp and I assume that the Infinity unit has line level out through one of the connectors. I would then need to run into the stock connector with the power from the amp to the existing speakers. I'm trying to make it as simple as possible, it isn't about making the audio loads better so I won't be running new wire to the speakers. Also, what can I do to get an antenna for the Nav system? I have several GPS antenna in my leftover draws but the connector isn't the same. I'm hoping that since this is a 6 year old Sorento, someone might have dealt with this before. Any info will be much appreciated.
