My initial impression of Nuvi 750-route display not what I hoped for

I finally got my gps-I decided on Nuvi 750. I was even initially impressed it somehow located where I lived even though it was only powered up indoors-strange. Anyway, not sure how to edit the home location as far as an actual street address. Anyway what I am impressed with is how well it knows where you are, even on an entrance ramp on freeway versus actual freeway. Satellite finding (start-up) is a little slow, several minutes it seems.

Anyway my main feelinsg now, are ,besides manual is very poor, I mean the start-up one is only included and the on-line one seems very minimal considering this unit lists for $700, is that there doesn't seem to be a lot of user options-i.e. route planning and display.

My main questions for garmin users, or any other brands also, is when you are "en route", there is no display of speed or direction. Granted I can get that by pressing one button, but I like the "default" map display when not en route. Is there a way to display the speeed and direction when going on a route? Does other brands have that-it bothers me enough I may sell this unit. Also, on simulator mode, which seems odd "simulate" is under "settings", as when that is on you can't do a normal route while driving, so I would think it would be more intuitive to have just another button for simulate after choosing a destination. Also when simulating, again the direction (west, etc.) is not given so it is hard to follow, not to mention SLOW. I wonder if there is a way to speed up the sim mode.
