I just receive this unit today about 3 hour ago . after play around with it and take it out for a short 20 minute drive , I think I get my money 's worth . install map to this unit take almost a hour . 1 . dvd setup copy everything to you computer . 25min 2 . Select state and it zip it or something . 15min 3 . copy map to i3 unit . -lrb- -lrb- 5min -rrb- 4 . acquire satelite . -lrb- ~ 5min -rrb- I be able to add . VA , MD , NJ , NY , de , pa , wv . I might have add couple more but I be not sure . I also add couple customer pous that I download from some site . screen size . I be afraid it might be too small , but actually it be not that bad . plus with voice prompt , all I have to do be glance at it from time to time to see if I be on the right track . Navigation . it might be the map , but sometimes when I pass a intersection , I do not see anything on my i3 unit . or the name be different . I be navigate to my office right across the street , but i3 tell I to make left turn and go around instead of just head straight . I have 2005 Civic and mount be kinda tricky . first , I place it lower middle of the windshield , but it be hard to reach . so I place it right on the center , it be easy to reach , but the cable bother I . I need to find the perfect spot to place this , or get battery . be a first time GPS user , I be not 100 % satisfied . may be I be expect too much for this price , but I think the whole calculating\/locating\/navigating \/ get from satelite could be little faster . but I be very satisfied for this price . I be go on a trip to NY tonight and we 'll see if it be really worth $ 300 or I should have pay couple extra for a better unit . -- Edited Nov 29 , 2005 . I come back from my trip to NY from DC . it be great . I lose signal in tunnel and in the middle of NY city , skyscraper , but it come back alive pretty quickly . I leave the unit zoom in , and it zoom out automatically when I be on highway go over 60mph . it zoom back in when I get off highway . Pretty neat . it also zoom in when I need to make turn or exit . the only issue i have be the map . it would be nice to be able to setup the map to show gasstation , restaurant , restarea , etc. . if I be look for mcdonald , I have to search and see map on every single mcdonald from the pous to see which one be on my way and not far from my route . another neat thing with pous be that they also provide phone number with address . no more 411 necessary . it be small enough to fit in my civic glovebox with the car adapter . I love it .
