SOFTWARE UPDATING IS HORRENDOUS...
For those who have a macbook, Garmin pretty much gave us the middle finger when it comes to terms of software update, you have to be running windows to update your units. Also, don't forget if you are using an SD card that it only supports 32gb and under or else it will not work, REALLY???
Come on Garmin, it cant be that hard to put together a software update for us mac users and I have no idea why there is a limit on the size of SD card, I have 4 SD cards that are 64gb or higher that apparently worthless to Garmin.
