what be great about it : Easy to Use & Understand ... Lifetime Maps ... Lane Assist be a Life Saver ... customizable ... Nice Interface I travel a lot , but where map and direction be concern , I be a dummy . I have always have problem in figure out where I be go , how to get there and how to get back . this be my first GPS unit and the process in select a good one seem confusing and difficult . call it good fortune , but after web research , I land on this one , and WOW , be I glad I do ! EVERY thing I have do & discover from the minute I get home and open the box have reinforce this great purchase . a few highlight . 1 . lifetime map ... rather than to pay $ 90 - 100 per year for map update , pay a little more upfront , get a unit that have the `` LM '' designation . with what little knowledge I have about GPS unit , this be my first great decision . 2 . Lane Assist and detailed `` junction View '' . keep you in the right lane , and a great split-screen view of highway junction as you approach they . as I say , I be a traffic dummy and these be the place where I always get lose , go or confuse ... but I have try this and it work . I just listen to what be be say , check the lane indicator and stay there until tell otherwise . I have the benefit of be able to test this in Los Angeles , San Jose & Portland - and I sail through each of these city with ease . 3 . customization ... when you go to the Garmin site , register and log in , you can then download different type of vehicle , voice and other nicety for you device . you can even create custom voice , such as you own ! map update ... the process take a few hour the first time . you do have to download they `` Communicator Plugin '' and the Map Updater first , after that , every thing go smoothly and -lrb- again -rrb- good for dummy such as myself . fit and finish ... during my search for a gp device , I look at all the major maker and find I find the look of the Garmin road and map a lot better than any of the other . I also like the stark design of the unit itself . it just look GOOD . this be a 5 '' unit and -lrb- for I -rrb- very easy to see & read . should you pay a little more and get a unit that also include Traffic capability ? for some , perhaps . I find this on sale for $ 127.00 and for that price , this be PERFECT .
