We are trying to update an old but like-new Nuvi 52 that has not been updated in a few years. Garmin Express seems to be working as expected, it finds the device, copies updates and shows "Update Successful!" but the updated versions do not show up in the device and Garmin Express then tries to update the exact same files all over again. Device storage at 47%. Have performed various troubleshooting steps:
- Deleted previous xml file and 'restored' device
- Turned off virus
- Installed Garmin Express latest Windows version as administrator
- Reinstalled Garmin Express as administrator
- Rebooted PC a number of times
- Tried different USB ports
- Used different USB cables
What are we missing here? How can we get this device to retain the updates?
