Yes, it needs to get new almanac data, just like it has never been turned on. But that is NOT the maps, just the satellite data. Internal and Mapsource maps should be ok since they are using different memory. It's your WP's, routes, tracks, and any special settings your had (such as NAD27) that will be lost because I guess the way they are stored is different now in order to get the higher numbers. As Bernie asked, all data needs to be backed up if you need it again. There are lots of freeware programs out there that will do that. I use EasyGPS; if you have Garmin Mapsource, it can backup those files too. ----- Original Message ----- From: Mike Griffin To: geocaching@xxxxxxxxxxxxx Sent: Friday, February 07, 2003 10:04 PM Subject: [GeoStL] Re: production 3.10 for Legend and Vista Rich, does this mean I need to set it out for 15-30 minutes and it will get all the standard maps that normally come with it? I would also assume that I would have to reload my Mapquest maps as well..
