After years of using a 66s almost exclusively for Geocaching, I'm having a ton of problems.
The problem is I can't view any information about a Geocache anymore. If I review it, or try to see the logs, anything like that, the unit freezes immediately on the "go" screen resulting in me having to pull the batteries and repower it on. Everything else not related to Geocaching is working fine.
My problems all started last night when I let Garmin Express update my unit. I am on software version 10.20 now. Before the Garmin Express update, it gave a error saying that my current.gpx file was an invalid filename and gave me instructions to delete it. I deleted it, ran the update and now none of my Geocaches work. Including the Geocaches that were on the unit before the update.
Things I have tried so far to fix it are I have deleted and added new Geocaches multiple times with reboots after each step. I use GSAK to handle my pocket queries and GSAK to export them as a GGZ file to the SD Card of the unit. I've even tried with new pocket queries using both gpx versions 1.0 and 1.0.1. Is 1.0 the correct best version for the unit? I've always used it without any issues.
I'm at a loss here. I'm really hoping to avoid doing a complete reset of my device, but it seems like that might be my only choice. I'm hoping and praying someone here has a solution I haven't thought of.
