The GT version we have has all the goodies. The one I like the most is BLISS. An awesome feature that works great. I even start to like the NAV system. It is not the best but when you know how to use it, it is not really that bad and has neat features.
What is BLISS?? The NAV would have been much more useful if you can lookup while driving. But I did find it very useful as it shows me the next upcoming gas stations, restaurants etc. My old TT GO 700 doesn't have that feature, though I suspect most newer GPS do.
Also, in addition to the little box that shows time of arrival and number of miles left, a bit more info would be very useful.
I'm too lazy to read the manual again, but what is suppose to happen if you press the SPEAK/NAV button and say "restaurant" for example. The NAV just repeats it back to me and nothing happens after that. Does it just lookup restaurant POI and display them on the screen?
