I purchase this for my wife for Christmas ' 06 . within 5 minute of get it out of the box , she have it up and run , just by use the Quick Reference Guide . she be very pleased with how , `` intuitive '' it be . we take we first `` road trip '' the next day -lrb- she be the navigator , of course -rrb- and it work without a hitch . the one negative be when the battery go low , and the unit shut off . I have to `` reset '' the unit to get it to start charge . I be hopeful Garmin will look into that . overall , she be very pleased with the Nuvi 350 , and that be what be important . good product !!
