[pct-l] Garmin 60CSx halfmile' map question

[Joshua Pinedo]

So yesterday I started the 4-6 hour map uploading process from Halfmiles'
guidelines.  I had about an hour left (it was uploading for 6 hours by this
point), and I just couldn't for the life of me stay up any longer.  I woke
up this morning and there was an error message and I was pretty distraught.
Has anyone experienced this? I saved my 24K Maps and The PCT overlays in
Mapsource.  Should I just go back to that same point and 'send to device'
again and hopefully not get another error message? will it take 7 hours
again or has some information been saved on my 4 G memory card?  Will it
just rewrite over what was uploaded or will it pick up where it left off? My
main thing is wanting to know if I need a new micro SC card or not..

sorry for all the questions..

first GPS ever


best,

Joshua
