I be a emt in a rural area where I have not live for very long . I need something to help I find my way through country backroad fast and efficiently , and this fit the bill for the most part . the main problem I have have be that it can take a while to locate satellite at first if it have not be turn on for a while , which in most application would not be much of a problem , as at most it be a minute and a half . the next be it do not turn with you , which can be briefly confuse if you have to take two quick turn , and change a lane in the process -lrb- i.e. a right and a quick left , I get stick in the right lane -rrb- . Speaker could be a little louder , as well . then the last be no flash -lrb- programming , or photography -rrb- . not much of a problem as it be not it be main purpose , but worth mention . the good part - re-route very fast and effectively , it detour I very well around flooding with minimal input from I . very fast web connection , decent signal . Touchscreen work flawlessly and input quickly . it be sleek , about the same size as a android , with very intuitive programming . have not use the camera much , but it be a nice touch , and 2mp be as much as I would need on a day to day basis . in short , it be extremely fast except when initially acquire satellite after be off for a while , have plenty of feature , and be very well program . it work well for what I need it for and be a great buy for the one day deal I purchase it for . at full price I would have expect a little more , however .
