I'm new here, and not sure this thread is still active. I bought the D5114 and I'm having some issues with installation. It has not been a smooth plug-and-play installation as I was lead to believe. The unit's harness is not fully compatible with my factory plug, specifically with regards to the connection to the factory amplifier. So I can hook up the unit, but I have no sound. I have e-mailed the factory and they have not been very helpful, I was hoping the eonon rep in this thread could give me a hand. Hoping to hear from you soon, or others who have encountered this issue.
