I be a fan of the Hertz Magellan Neverlost system , but the bi-modal review of the Magellan Systems give the impression that there be prodcution quality issue . next , I be go to go for the Garmin 2720 . it can be fit with dead reckoning , but need wiring to the car . review make I realize , my main reason for buy a gp be not to use on my car , but on business trip and hence rental car . so portability be key , and the Nuvi have the best form factor . to lug a 2720 -lrb- with laptop , file etc -rrb- on business trip would make thing just the bit more heavy . in addition to the good point give by other reviewer , I must say the mount be excellent . it stick well and because the Nuvi be so light , the mount do not have a lot to do to stick there . also , the cigarette lighter power can cleverly be plug straight into the mount and not the unit . to mount the Nuvi , you have only to flip the antenna up -lrb- activate the gp -rrb- and clip it on . it power up straight away . then , when you get out , all you have to do , be press a small clasp release on the mount and out pop the Nuvi . it even switch itself off after 30 seconds . you can also put the Nuvi in `` search mode '' . while drive on the free way look for food or lodging , you only have to press `` where to '' and then press say `` lodging '' . the Nuvi give you a list of hotel , motel , hostel near you . it also provide distance and arrow show whether they be ahead or behind you current position . the list update itself every few minute as you move along . see something you like ? just press it and the `` go '' button and Nuvi take you there . it be a life saver when we be travel long distance late at night and need somewhere convenient to stay . finally , this be one gadget that my wife love . when on holiday , she invariably end up the navigator . its stressful for she and thing get heat up when I make a wrong turn require difficult new instruction on what to do . Nuvi have change all that . she just sleep through , as the Nuvi announce its `` recalculate '' the route . but indeed , you don `` t get a map which you can load on you pc , there be apparently no way to plan\/alter route on the Nuvi prior to make a trip or to keep a record of you trip . Garmin have be excellent in address user feedback , so I be hopeful . BTW , I do not use the other function such as mp3\/calculator and would prefer the functionality on the GPS be improve rather than these function . but that be just I since I still use a pda .
