One other thought for you that may or may not be relevant. I recently did a battery change on my HCx, and when I powered the unit back on, everything was gone! Maps, tracks, and routes... the only thing there was the basemap - I was ticked. I put the thing down and didn't look at it for a couple of weeks, but the next time I did, I noticed that my memory card had come unseated (I must've bumped it when doing the battery change). Once I clicked it back in, everything reappeared. I'm not sure where the card is on the 60, but thought I'd offer this up. Hope you figure it out.
