I had that problem with both the 400 and the 500. I searched the forums and found others with similar problems who sent theirs in to be fixed. This was last fall/winter. I just started taking the SD card out and putting the files directly on that. -Tracy of MutherAndSun ----- Original Message ---- From: Jesse Brannan <stlredrocker@xxxxxxxxx> To: geocaching@xxxxxxxxxxxxx Sent: Friday, October 17, 2008 9:21:42 PM Subject: [GeoStL] Explorist 400 not going into file transfer mode My explorist 400 has mysteriously stopped going into file transfer mode. I can still charge the battery via the usb cable but will not connect to my computer. I have turned it off and back on after a period of time, unplugged completly and plugged back in, drained the battery and recharged, reset to factory defaults, basically everything I can think of. Anyone else with an explorist experience a similar problem or just any other suggestions that I haven't thought of Jesse "What is understood, doesn't need to be discussed" __________________________________________________ Do You Yahoo!?
