I have hardly used my Oregon 300 in the past 6 years. Last fall started making experimental layers with the current data from USGS, Census and OSM. I did many hundreds of uploads to the Or300 using sendmap2; some without a custom type file, others with. The .img file(s) were deleted from the Or300 after every one or two file were uploaded. Three days ago I stated to get a 'memory full' message almost every time the Or300 was connect to my computer USB port. Initially a file sent using sendmap2 was OK; then after a few uploads the Or300 would not show the file on the map select menu (it would show with the proper upload/build time using edge). The Or300 now goes into USB access mode about 6-7 seconds after the 'memory full' message appears whether 'OK' is pressed or not.
There are no waypoints, tracks nor geocashes on the Or300 nor on the microSD card. The OR300 has the Garmin basemap and the MicroSD has my state map from a decade ago.
Free space on the OR300 is 900Mb of 1Gb and on the microSD is 3.7Gb of 4.0Gb. Neither removing the microSD card nor using another changes anything, nor does trying two other USB cables. The 'memory full' message also appears when in 'battery mode'. Also tried another computer, transferring the sendmap2 gmapsupp.img file via edge to the microSD and transferring other .img files made years ago - none work.
Any suggestions?
Wore out unit?
A corrupt file? I have done a 'factory reinstall' twice.
