I have (had) a fully functioning DRiveAssist 50 and after attempted Update, the GPS will not recognize the micro SD card. (Yes... it's an OLD unit now) I replaced the card and NO improvement. I did the factory RESET and tried the map update. Garmin Express stopped connecting to the GPS unit. Called Support... and followed their steps... and EVERYTHING got worse. As instructed, Reinstalled Garmin Express, Uninstalled/Reinstalled the GPS Unit but unit no longer found. Garmin said the GPS is now dead. (said this was the first generation of their new Update) Said, Buy a new one, here's a discount code. DO NOT UPDATE YOUR WORKING DRIVEASSIST UNIT!!!
