@iffis76, you may also transfer your routes and favorites between garmin pc and xt via a "current.gpx" file (without mapsource). on PC, this file is in the " #:\Documents and Settings\<YOUR_USERNAME>\Application Data\Garmin\GarminMobilePC\gpx\" folder. it's renewed automatically upon closing the garminpc (if routes, points etc. were added/changed). to transfer pc routes to phone you copy pc's "current.gpx" to "#:\garmin\gpx\". then open garminxt - <tools> <manage my data> <manage (left soft key)> <import gpx>. that's it! to transfer from phone, you have to <export gpx> (same menu) first, i.e. update "current.gpx" manually.
