Hey LEONARD JUL,
Does the radio function okay and it is just the display cutting out?
I would first check the interior light fuse as explained in the fault diagnosis guide attached below.
Please can you remove the navigation display and check the power and ground to the unit when it is on and when the fault occurs?
Are you losing power?
The accessory circuit may be the problem.
Let us know how you go with these tests, any questions to clarify anything please do not hesitate to ask.
