I dont have any cases for this but you might want to look at this for your gps issue.
You might have inadvertently changed some of the setup options on the PDA so the best thing to do at the moment would be a hard reset. Fujitsu-Siemens Pocket LOOX N560 hard reset soft reset This will restore the unit to factory settings so make sure you back up any files you have loaded onto the PDA. Once this is done press start – settings – system tab Select GPS and set the GPS program port to Com 0. Don’t change the hardware port and make sure windows is set to manage connection automatically. Once this is done go to the connections tab of the settings menu and select beam. Ensure receive all incoming beams is unticked. The GPS locator program only works if you have com 0 selected. You will see the amber light at the top left flash to show it is looking for sats. The first time it connects can take up 10 minutes as it is looking for sats from scratch but all subsequent ones will be quicker if you use it regularly. If you add any other GPS programs you will need to set the GPS setting in the new program to Com 0 so that matches the program port on the PDA. Basically you’re telling the software where to look for the GPS signal.
