Garmin Edge 530 and Varia RTL515 keep locking up

Had you just completed a ClimbPro climb when it locked up? 

Is the percent incline field on your Elevation Profile datascreen?

Sadly no, the 530 cycles through all the screens while i ride. It's just odd that it froze on that one twice.

I have gone twice alone with no issues...so it seems that when I ride in a group, the radar gets ghost images from other riders?

GD thing jammed again...same screen, riders behind...this sucks Garmin...get it sorted

Same here, I've got the 520 plus and my bontrager ion and flare lights keep dropping off and connecting to my riding buddies garmin watch. When I attempt to set the lights to manual mode rather than auto on the 520 it does not work and acts the same way.
