I updated my nav sw with v26 shortly after it was available on my 540i. I decided to downgrade to v25 because I was constantly getting faint black lines in the graphics. After loading the v25 software, the nav computer went to the euro mode where the emergency and accept menu are no longer there and I can select meters and yards. But after turning off the car, I noticed the next day that my aux ventilation is gone and so is the VIN from the service menu. Anyone know what happened? I guess I could always have the dealer look at it but I love not having to deal with the accept menu.
