I'm so fricking angry now. Just decided to finally install the updates to my 810 and my wife's 510. My 810 update appears to have gone smoothly without losing any bike profiles or other data. However, my wife's 510 completely reset, loosing all her data. To make matters worse, now I have to set it up from scratch and the ONLY GENDER OPTION IS MALE!!!!, can't set her age, height or weight in the initial set up procedure either. If i just fake it through that process and try to set it up from the settings menu, it takes, but then when I go to the next subject (i.e., gender, then back to choose weight or height) each category resets after I set the next one.

Damnit Garmin!!!! what the hell is wrong with you people that you have such crappy software. I'm two seconds from throwing this 510 as hard against a wall as I possibly can. Only reason I'm not is that there isn't a garmin software engineer standing against it to target.

Guess I now have to go through the pleasure of calling these useless idiots to try and fix their useless software update. Of course, they don't work on the weekends. Just during the time when I'm at work so doing this from home is not an option. Life is too short to deal with Garmin. I'm done with them after this. Completely done with them.
