New Guy w/ a Garmin C340...

Hello All.

I'm new here (obviously). I received a Garmin C340 for Christmas from my Mom. Actually, it's a gift to share with the fiancée too.

I used it for the first time yesterday while traveling to my aunt's house. It's somewhere I've been before, and the c340 took me the way that I normally go.

I was very pleased.

On the way home, however, it lost satellite reception about 5 minutes into the trip, and picked it back up maybe twice for less than 30 seconds on the way home.

We tried the turn-it-off-then-turn-it-back-on thing which seems to work with so many electronic gadgets any more to no avail.

Is this a frequent occurance with these things?

Also, I downloaded some POI info... some from the Sheetz.com site that alerts you to their locations, and some form this site for Get Go locations.

Am I correct that these are just *.csv files?

I can create my own easily then, no? Using Google Maps to get the lat/long and then just slapping in the address?

Is there any way to import a CSV file into my favorites? Say I have a family address spreadsheet?

Also... My cousin has a Garmin that looks like a walkie-talkie... and frequently does geocashing. Is that something I can do with my unit, or is this a "stay on the road" one?

Thanks in advance!
