I have had my Garmin 530 for about 2 months and am not impressed - when creating a ride "Create Course Function" and then using the navigation it will almost always fail to complete the loop, comes back with do a U Turn, Off Course and then when trying to start over have the same issue... rode on Sunday over 100 kim first 50 great, and then failed defaulted back to saved locations HOME to return which took me back exaclty the way I had just come..... what are my options???
