MS6 2007 Navigation is stupid !?

Hi All,

I recently bought MS6 and I am really disappointed in its navigation system.
It is absolutely stupid piece of electronics I've ever seen.
Any navigation around 200-300 dollars beats it in both functionality and features.

First of all I've decided to check points of interest so I just went into Search by name and entered WALMART.
It didn't find Walmart store, but found other walmarts (some financial institutions) about 300 to 500 miles from my location.

Then I tried Fry's. It found Fry's automotive in Pasadena !!? WTF? Then it showed Fry's foods somewhere else but no Fry's electronics store.

Then I went into shopping category of the menu and foiund there are only two categories: grocery store and shopping mall. WTF!!???
So if the store Im looking for is not one of those I am f*****d!!

Is Navteq THAT stupid or is it my instance of navigation system is that stupid?

Does anyone know how to upgrade the software that this navi runs?

BTW I did not even mention that this piece of crap does not even have a touchscreen, no entry prediction and sutocomplete whatsoever!!!
