Took my 2007 Cayman (Base) out of storage and am having issues with CDR24 base unit sending what appears to sound like audio feedback. Almost sounds as if base and volume is turned up on max. Car has been on trickle charger (Porsche CTEK) since Nov 1. On first door open a low base rumble, quite loud, was coming through speakers (radio off, key out of ignition). Car started without issue, yet what sounds like audio feedback is constant. Feedback is present with key in or out, radio on or off. Radio does turn on and all functions seem to be working. When radio on, you can slightly hear broadcast on station but is overpowered by a loud low base rumble. When radio off and key out of ignition, feedback continues for about 2-3 minutes then shuts down. Upon opening the door, feedback starts within a few seconds without putting key into ignition or powering up radio. Car continues to start without issue, drives fine and has no error codes. Have not tested the battery nor disconnected at this time. Looking for some suggestion or guidance. Any assistance would be appreciated. Thanks!

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.
