3597 lost auto-zoom out on freeway (while not on a route) after navigating a route

 

Have the 3597 for quite a few months and love it.

I have observed one annoyance however.

Starting from a hard-rest or set a new locale, the auto-zoom would function properly, zooming in to a medium level at local streets and out at freeway driving, zooming really in at free ramps, until I let it guide me to a destination.

The auto-zoom functions work normally while on a route.

While not on a route, the auto zoom still works, except on the freeways. Getting on a freeway, the map zooms way in on the ramp to the level that I can see the outlines of buildings (normal). But it stays there without auto-zooming out even after I am already on the freeway. I need to manually zoom it out.

So far I found the only ways that I can restore the auto-zoom-out on the freeways are to do a change locale through the developer's menu or do a hard reset.

Any one else seen the same issue and better solutions?
