I'm at my wits' end with this strange problem on my Porsche. When I start the car, the navigation system makes a loud, random static noise for a few seconds before settling down and functioning normally. It's more than just annoying; it damages the speakers. I tried rebooting the system and checking the connections, but the noise persisted. Does anyone else have this strange noise problem?

That static noise sounds very irritating. Based on my experience, it could be due to interference in the audio connections or a problem with the navigation system's audio processor. Check for loose wiring and ensure that the connections are properly shielded. If those checks fail, having a professional inspect the audio components for any flaws or signal interference may be worthwhile.
