Nissan Navara having a funny turn

[Wheelrepairit]

Have a Navara, 56 plate, brought from new, 44k miles covered.

Its the adventura model, ie with built in sat nav and bluetooth.

Now ive driven this truck all over europe and its been faultless,apart from one thing.

4 times in the time ive had it the main screen and stereo just crash, go blank and stop playing, for about 10 secs, then just come back on no problem.

Strange thing is this does it at only one place, on the M11 roundabout by stansted airport, just by the entrance to the services.

I cross this junction 100s times in a yr, yet only done this 4 times.

Any ideas

Its not a worry, just strange, just wondered why.
