I be a Realtor , so I be always go to new place , and down street that I be unfamiliar with . I guess you could say that on any give day i be show 8 different house in different location . no problem , I just punch in where I want to go and I be there , easy . I 'll break down some of my likes vs. dislike : like : - when I be sit in traffic , I can either hit the detour and it will pick a new route - or I can just look at the overview of the GPS mapping itself , and look for parallel side street . - there be nothing I hate more as a realtor than have the street sign miss for a street . not a problem anymore ! rain , snow , nighttime , I can always see the street come up on the unit , too . I do not have to squint to see the upcoming street sign -lrb- my eye be horrible -rrb- . - if you miss a turn on you program route , the unit will automatically refresh with the best new route . - if I be in a county over from I , I can pull up food , gas , ATM 's , hotel , etc. and it will find the closest one , or I can search by name . - the unit show you you speed , distance to you destination , distance you have go , minute sit idle -lrb- in traffic -rrb- , avg . mile per hour for the trip , and destination time . the destination time be important to I when I have to be at a meeting ... I 'll know how long it will take I to get there , and it be pretty accurate . - it will give you a voice command to `` turn right in 300 ft '' , or `` turn right and then stay leave '' for example . Easy to hear . - I always drive with little fuel -lrb- I be always on ` e ' -rrb- . I love push the fuel icon and it list all the nearest gas station and they distance , location , and phone number -lrb- call for fuel price if bore on a trip -rrb- . it will also map for you how to get there . - it also have , ATM 's , restaurant -lrb- you can search by ` type ' of food - and it will have phone # 's -rrb- , or you can just punch in the letter - like WALMART for example . - no problem lock onto satellite , in any type of weather . - it have a internal battery , so when you turn you car off to put gas in , it 'll stay on & keep you current destination on . - want to stay on MAIN road in unfamiliar territory ? go to ` option ' and tell the unit you be a semi-truck instead of a car . - the quickest route be the default , but you can switch to shortest -lrb- in mile -rrb- . dislike : - I wish it would tell you when to turn a little earlier . it normally tell you to turn left or turn right in 300ft , but this may be difficult in heavy traffic . - do not give x axis or y axis coordinate . no altitude , either . - you have to take it out of you car when you park -lrb- or lock in glove box -rrb- everywhere you go , so it will not get steal . of course this would be a drawback for any portable unit . be you really go to find a unit that do all of this for under $ 300 ? I have search for the last 3 month and have not find a better unit for the price .
