To be honest, I don't completely mind it. I would prefer the option though. Some folks -- my wife included -- don't read maps that well. She can't maintain her orientation unless the map's pointed in the direction she's going. It's a nightmare when we're travelling w/o a GPS, because she can't tell right from left unless we're going NORTH!!

Perhaps you should switch to the 3D mode? I personally love the 3D nav with auto zoom. I love seeing exactly what the road I am traveling on looks like. I just got back from a 9hour road trip to an area I had never been to before, and besides not knowing the new development in the small town & thinking you weren't allowed to turn left on a highway, it worked great! The nav was spot on (unlike the D3), and I could see very clearly which road to to turn on, if I was going under an overpass, etc. I really liked how it would tell me which lanes to stay in as highways split off. Yes, it can be finicky from time to time, but I've found that hitting the Map button, or hitting the info button then the map button fixed all my problems. (which were admittedly caused by me fiddling with the unit's different functions.)
Using the 3D mode with auto zoom can be confusing, and it took me a little while to figure out that it would zoom out to 2D if it was >2miles to the next turn, merger, etc. Overall, the Nav makes the other quirks worthwhile for me.
