An emergency-call warning after work near the roof or aerial needs the repair history included. It should not be treated as an ordinary radio reception problem merely because components share an area.
Preserve the exact message
Record the affected functions, work performed and full scan. Ask the repairing garage which connections or components were disturbed. Do not make a test emergency call unless following an explicitly authorised provider procedure.
The workshop should assess the vehicle-specific system and explain whether any service availability is affected while awaiting repair. Avoid coding out the warning. A clear record helps distinguish installation, communication, supply and service-related issues without assuming that an entire telematics unit needs replacement.
