My BMW Navigator VI is possessed

[BobAin'tStoppin']

Getting home from Colorado, my Nav 6 works properly. I had the entire trip loaded in from Base Camp with each day a separate file. I did have one thing on the way home. When the low fuel light comes on the gas icon comes up on the nav screen. Touch that and search for gas stations on my route. I pick one about 20 miles ahead and add it to the route. But the nav put the station at the end of the route instead of the next thing. So my arrival time went to midnight and the gas station was 500 miles away! Now, I was driving at the time and so didn't get to really study what or why this was going on. Did I push a wrong button? No idea, so I just got to a gas station the old fashioned way. This isn't a problem on the main highways, but could become on in the back country. Any comments?
