I have a Tecvox TD712 InDash and I am missing the connector that plugs into the back of the unit after being spliced into the car's wiring. On the back of the unit it labels the connector CN1, I'm not sure if that is a standard part, or unique to my unit. Tecvox's 800 number doesn't work, and they don't return my eMails. Any help at replacing this plug would be appreciated.
