Garmin 2720 will not load maps after doing a map update (NT 2015.20) yesterday. Cycling between loading maps
(dimmer screen) and power up (bright screen). Was working fine before attemp to update maps. Unit did shut down during
update at 6 minutes before it ended. Now neither Mapsource or Garmin's site ''sees'' the unit. I know
this update is compatible since I have another 2720 (withh the ill fated lifetime updates) working
perfectly. I did do a hard reset (Power up while holding FIND down 5-10 secs)
