in term of gp functionality -- this unit work fine . it have a pretty good display , navigation work well , etc. . however , I have to return this unit becuase you can not store address as `` favorite '' like many other gp unit -lrb- include my older nextar c3 -rrb- . you can store `` home '' and `` work '' - that be it . -lrb- and while these two ` favorite ' can be rename -- two just do not cut it for I -rrb- . also , while you can review and retrieve a address from a `` history '' of recently-travelled destination , these will scroll off eventually and then those address have to be re-enter . too bad -- a really important feature that be leave out , and a deal-killer for I . Wish I have know beforehand . if that do not bother you -- then I do actually still recommend this gp -- the price be sure right .
