I did not order the Tech package on my 85kw, Blue MS. When I looked at a MS at the Raleigh service center the mgr told me my car's screen would show maps and would "track" my location while I am driving but would not have the capability of navigating me to a destination and would not show any other navigation features such as distance to destination. First question - Is my understanding of what the service mgr told me correct? Second question - If I am correct, is it safe to assume that full navigation capabilities would be a software upgrade only? Third question - Has anyone heard about such "a la cart" upgrades ever being available?
