Hello, our Omega Caravan (BJ 2001) has the Bose sound system in it. Navi, radio, onboard computer etc. everything is displayed via the display. For 2 days the display has been exposed. First it showed gray longitudinal stripes, then it began to make like a light organ always new patterns. Suddenly also the normal display appears again, but shortly afterwards disappears again…as if a wobble contact was to blame. The radio works normally over the stored numbers, but the Navi can be Does any of you have any advice on what this might be (and how to fix it???) Thank you in advance!
