Just purchased a Pinnacle last month, and alas we are already having issues. When you start the car, there is sound from the radio for a few seconds, then it goes silent. The radio is turned on - SXM will switch to a new song or my audiobook playing through CarPlay shows that it is playing. But there is absolutely no sound. I’ve even tried the car with no phone at all thinking maybe it was a phone connection issue, but no still a few seconds of sound & then silence. Any ideas? I found some YouTube videos showing you how to disconnect & then reconnect fuses from the AMP box under the passenger seat, but hesitant to try this.
