problem screen interference !!!!

Psylmie

Hi to all Zdists, my main screen always has interference when I drive, flickers, line on screens, .... . Pressing a key returns the screen to normal. Pb only while driving and when I go to the INFORMATION/TRAFFIC screen. As if a pb linked to the GPS degrades the display quality (by frequency approximately 1s)
I dismounted console and disconnected screen and reconnected but still not concluding this failure. I tested RAS keyboard.

Anyone have an idea, pb since last July when returning from vacation .... Can the GPS sensor generate screen display degradation?

Model July 2009 display DP7W-1012E Xanavi Informatics Corporation (28091 1BP0B). Of course not found on the internet and Ebay !!! I just bought a 28091 jk61a - TR-LM7WB3N from 2009 on EBAY, I hope it's compatible???

If a Zdist knows about it?

Thank you community
