Customer Question

I have a 2002 Chevrolet Silverado2500HD with dual batteries. My AVH-X7700BT will randomly will not power up unless the harness is disconnected and reconnected. Is there a problem with the head unit or the wiring harness?

Hi, thank you for contacting My name is Russell. I will do my best to provide the right answer to your question. The power connectors in the wiring might be slightly dirty. Scrub both sides of the power connector, with a clean dry brush, and wipe down the connectors with a dry cloth, rubbing until the metal shines. That may help, by improving the connection.
