Hi, installed 7100nex, used micro bypass...all was well however; after some time..upon turning on the ignition to start vehicle,  unit powers up normally, transitions to splash screen then blank.   No activity, lights are on along controls at the bottom but no more activity.  Can't seem to find anything in the instructions/trouble shooting section, any help/ideas?    

7100nex does not need a mircobypass

its a software bypass
