Bill, put things in perspective- brand new Landrover GPS factory option- $4,500, for that I can outfit your Grand with the biggest baddest meanest stereo/DVD/CD/MP3/TV/GPS in a factory like enclosure which would you prefer?
So there is no current factory option? so what?
Oh, and no-one does a factory GPS per-se it is a SAT-NAV system all of which have varying degrees of inaccuracy, due to the age of the maps and the regularity and ability to update- check out ANY factory SAT-NAV system going into apoplexy as you drive the new Kiama bypass
.
Finally having used both street director+memory and SAT-NAV around sydney give me the paper and addled brain any day! Granted when I go to other major cities SAT-NAV is useful. but how many of the soccer mums buying these cars that must have it actually drive more than to the school and back anyway?
my 2cents worth
