never put your home address in!!!! use a nearby spot instead. there has been a rash of subtle vehicle break-ins that are nearly indistinguishable where either nothing is stolen or something little, bizzare is taken. each one of these vehicles had a gps unit. the thieves simply got the home addresses and waited for the opportunity. 
my gps is a love/hate relationship worstened if my hubby is driving "somewhere" he's driven ,been a passenger in a car, or flew over within his lifetime. typically, like Moses whom never conferred with a map, he'd insist everything looked familiar. I always google Thomas Brothers (never mapquest...shuddering...). Our adventure starts with him lost, we checking out new areas, him muttering that maybe we should use the gps. i turn the unit on. we backtrack for a while, then halfway there,(usually in a valley or too close to the airport or on a day of the week which ends with a "y") the signal.is.lost. there's a 15 minute window where hubby gently cheerleads himself in not needing guidance. ends with a wistful commentary of the simplity of maps (he's seemed to forgotten the stacks.of.unfoldable maps the size of tablecloths and the 300 paged books where our destinations were on the cusps of the right hand corners of page 98, right top of 22,right top of 231, middle of 63, and adhered to a melted Lifesaver spewed by a now grown child on the folded second to the last page). This is when I whip out a freshly printed, accurate map.
gps's should be called P.A.L.: pack a lunch...
