I purchase a 760 in 2006 , with the promise that update would be available on a regular basis . several time in 2007 , the unit itself prompt I to go to magellangps.com for new update , but the website say each time that the update wold not be available until `` x '' , x be a few month in the future . but yesterday , there be a update available . for $ 80 -lrb- well , I could live with that if it be a good update -rrb- , but - a really , really huge but - it be not available by download , and the dvd they offer could only be USED on a pc !! I be stunned , and call they customer support , which confirm that I could not update the unit on a APPLE COMPUTER ! what a huge ripoff . I now have a $ 300 paperweight ... never again !!
