If you adjust it to do so. Adjust the up slider all the way right and the down slider all the way left. Here are some images (sorry for the crappy blurry images but you get the point):


Hi Alex,
Your smartzoom design works wonderfully if you don't want to see the sky, reaching the same performance as the factory setting, for those that don't care about the sky, it is perfect! However, if you want to see the sky like in all Abb's snapshots, you would have to set both sliders all the way to the right side, at '90' for both. At this setting, smartzoom no longer works as it should. Please try it out.
In the link that I provide here: Smartzoom with sky based on IDT's mod, please look at each sequence vs the distance to turn, it show correctly the sky before reaching 800-1000 m, than tilt-down (perfect) and zoom-in (not perfect though).
Abb argued in the past that the smartzoom mechanism was locked somehow, but I firmly believe that it simply requires some minor tweakings in your mod, in order to render it perfect!
I however concur that modern navigation devices likes TomTom, Magellan and Garmin, to name a few, work exactly as in your mod (without the sky); but with iGo, we have a chance to see the beautiful sky, so I think that it would worth the effort to blend those features together. I just can't accept to sacrify the smartzoom in favor of the sky. In my mod based on Abb's v2.75 (also based on IDT's), it is almost perfect in this chapter except the zooming-in also requires some tweaking. I will take a look at it when I have time.
Just FYI, in the poll that I setup in my thread, there are 10 out of 12 prefer or use smartzoom, so even the sample is not huge, it is certainly not a minority.
Please let me know whether my explanation is clear. 
Thanks!
