After 5 years flawless performance my 705 is doing something weird.
About a month ago I plugged it into a Mac to upload gpx files. After riding them I deleted them (on the Mac) and replaced them with the next upcoming rides gpx.
However....on firing up the 705, the old (deleted) files were still there!
Problem is the 'saved rides' folder is now so full that when I open it the unit freezes at 90% so I can't even open a saved ride to navigate.
Any ideas or should I just pull the trigger on an 810?
