previous review highlight the many plus and a few minus feature , but as a moderately technical , but always lose person , I find the Garmin V to be my salvation . I like the `` find '' feature and the ability to find destination and route to they in a battery-saving `` inside mode '' before set off .  best thing - easy to read display -lrb- backlit with cigarette adaptor for night -rrb- give several advance warning of next turn . go off the suggest route , the unit immediately recalculate to you destination . waypoint can be easily set to retrace a route . set up HOME mean I can easily find my way back without wander as I have in the past .  the downloadable map be up to date and point of interest as restaurant , bank , gas station and hotel will be very useful when travel . the 19 mb of memory be the only downside . I can load all of the SF Bay area , but if I go to another area such as Sacramento or LA , I will have to do some swap -- I consider that a very minor inconvenience .  i love this unit - it be everything I could ask for at a reasonable price . my husband like it as well and be amaze the satellite access be free .
