Anyone have this issue - 92' nsx with factory cell phone. When I start the car or turn the key into the "on" position, I will get a beep from my center speaker, with the beep sounding like a button on a touchtone phone. The strange part is that I disconnected the cell phone components (phone physically removed) almost a year ago and never heard this beep until recently. Center speaker was working fine during that time and is still working great when I listen to the radio. Car was serviced prior to the start of the beeping, but no service was done on the interior, only transmission related. Is it possible a plug got "reattached?" Can you disconnect all the cell phone components, without loosing the center speaker?
