this be a excellent unit ! I have purchase the Garmin V Deluxe package with some trepidation as review I have read of it be mix . but I can honestly recommend it without reservation , have have it and use it for a while now . the quibble I read about the time recalculate route once off a plan route do not seem right - give 30 seconds or so , the machine recalibrate and calculate . battery life be good , and acquisition and lock on to satellite be also excellent . in a battery save measure , the backlight be turn off by default - I do hate that , but it be a very small problem .  the unit be smaller than I have think , and very light . it easily fit in a coat pocket . I like this unit - if you do not require a color unit , talk direction , or a larger screen , this will fit the bill very , very nicely .
