Hi, I am’s again. would need your help After I received my new XC 90 on 03.02.05 the following flaws occur : 1. From the beginning the turn signals do not flash evenly, there are partly double or triple flashes. 2. Yesterday I had appointments in Berlin. On the driveway (interval circuit ) the disc wipers partly did not wipe back to the beginning position, but stayed on the quarter of the disc height, until then the normal wipe interval started and after 10 minutes the same happened. 3. In Berlin ( Mileage : 1000 km ) we wanted to use my Navi system. However, the screen remained dark. Even after several turns on and off of the system it did not get better. Only after the complete turn off of the engine and restart functioned the system again. 4. On the return trip the Navi system and the radio fell out simultaneously during the ride, in order to restart after a few seconds. 5. Today my BC has played crazy and has always jumped back to the menu point before. Furthermore, the screen was dark again, I did not have to be able to diagnose a few of my friends. Maybe I have a problem.
