h8roads Posted January 29, 2017 Report Share Posted January 29, 2017 I have a Jeep Wrangler and used a navtool bypass with my esky camera to get it working with my factory nav unit, no issues at all. After upgrading to a 7200nex with IDatalink Maestro all I get is a black screen when connecting to the brown BC IN. Any ideas on what I'm missing? Power is good and connected to reverse light.
