My radio cuts in and out over small bumps when driving slowly. I’m assuming I have a lose connection to the antenna cable. Does anyone have a diagram of the connections in the trunk to the antenna? It’s either there or up at the radio in the dash. I didn’t have a Vastech BT unit installed recently, but I don’t think they had to take the radio out to make the connections, so I’m leaning toward the trunk are to check. Thoughts? Diagram?
