Look for any damage to the coaxial cable.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the faults from the 4R radio navigation computer memory using command RZ001
Fault memory.
Check the number of satellites received from outside, with the system switched on for
10 minutes, followed by a new check with the diagnostic tool.
