I buy the Garmin 680 because to save time -- time lose when find a location and time lose when rot in traffic . the other feature be more like a bonus to I . the 680 be excellent at navigation and its screen be super bright and readable even in the Arizona sun . the screen also respond well to my touch , to my surprise . the voice prompt be nice as well as be many of the configurable navigation option . now for the bad . I be most frustrated with the MSN Direct part . it be more of a after thought than a smoothly integrate feature . the problem with the MSN Direct feature be well document : - require the FM Adapter so you can only use it in the car - datum update -lrb- especially traffic -rrb- can take up to 10 minute or more . keep in mind when you start the car that you have no traffic datum , so by time you hit the freeway , you may not have the datum . - the MSN Direct overlay icon be small and unclear . - the MSN Direct info only overlay on the lame map instead of the primary map . - the Garmin route algorithm do not factor in traffic when route a optimal route . -lrb- note it do factor in road closure . -rrb- I really need that traffic datum since there be multiple route in Phoenix area . when the traffic datum be there , it have be pretty accurate thankfully . the good news be that about 90 % of the time that I need traffic datum , it be there . as for the gas datum , some people argue that this datum pay for the MSN Direct subscription so it be worth it . Bah ! my observation be that the cheapest gasoline station consistently remain as the cheapest gas station . and when you can find a cheaper one , it be out of the way not worth the time to get to it . if you can afford the price for this unit , then you be probably more interested in save time and not save $ 0.04 a gallon by drive 10 minute out of the way . I would really like to see Garmin pipe the traffic , gas , etc. datum over satellite or cellular instead of FM . anyway , I doubt I 'll renew my MSN Direct unless they give I a nice deal . a few other complaint ... if you load up a fast memory card -lrb- 2gig -rrb- with mp3 , this unit take a super long time to show you the initial map . why would not garmin give priority to the navigation and then worry about mp3 afterwards ? the point of interest as also miss a lot of established business . I would also like to see a better pedestrian mode such as show a trail that you walk -lrb- great for return from a hike -rrb- . in the end , for automobile navigation , the Garmin be a great product . they need to think through some of they little feature and also figure out how to better integrate real-time datum like traffic however . with rumor of Apple thinking of add navigation to the iPhone , Garmin need to step it up and offer apple-like usability in all area or they be go to get smoke .
