Just wondering because this is my first expierence with this and I found that my xl335s wasent finding a fix on satellites as fast as it used to so I started reading the forums here and found that some people had an issue like i did that was fixed by going into the device and deleting the contents of the ephem folder.....then deleting the ephemeris folder stored on my computer then running the update thus finding the newest update and installing it on my device (I did notice that there was 3 files in the ephem folder on my device unlike when i deleted the contents of that folder b4 the update it only had 2) Now im finding fixes quicker but do i have to do this every week or has the problem been fixed and will it now update through home like its supposed to?
