While I've done a lot of reading about the F90BT, I haven't had a chance to play with it, until today. Because of my research, I knew going into it that the navigation only had a 3D mode and a 2D mode (without track up). However, I didn't realize how big of an issue that is probably going to be for me until seeing it today.
I've used an external garmin unit for the last two years and the only mode I have ever found useful is the 2D track up mode. However, I was hoping that the 3D mode would suffice. What I found, by having the unit demo a route similar to my daily 40 minute commute, is that the 2D mode would be frustrating because it is counterintuitive. I don't want a unit that shows me driving in different directions on the screen other than up, hence the reason that most navigation owners like and use the track up feature. Therefore, I used the 3D mode and the problem with that was that it shows much less detail and on a longer route (such as my 40 minute commute - 35 miles or so), it doesn't allow me to zoom out as much as the 2D does. The 2D mode allows me to zoom out so that I can see where I'm starting from and where I'm going to and many ranges imbetween (not so with the 3D mode).
My question to those of you F series owners - is this not something that also bothers you or is it something that you just learned to deal with over time? After today, I'm thinking that this might be a deal breaker for me but before I make that decision, I figured it would be good to get opinions from people who own and use the unit on a daily basis.
