104 Rino ® 130 Owner’s ManualAPPENDIX > TRANSFERRING MAPSOURCE DATATransferring MapSource DataIf you have purchased a Garmin MapSource CD-ROMmapping program you may want to transfer detailed mapdata before beginning use, to provide your unit withmaximum Find features and mapping capability. TheRino 130 accepts up to 24 MB of map data from mostMapSource products. It is not possible to transfer 3rdparty maps into Garmin products.You cannot view multiple types of MapSource data in thesame location at the same time (one replaces the other ifthere is an overlap). When you leave a MetroGuide areafor example and enter the area of a topographic map, thedisplay changes to contour lines. The same is true whenmoving from a topo map to a MetroGuide map. TheBlueChart maps are at the top of the hierarchy and willreplace any other map information. Here is the list of thehierarchy for your reference:1. BlueChart2. MetroGuide3. Fishing Hot Spots4. Points of Interest5. U.S. Waterways & Lights6. U.S. Topo7. Roads and Recreation8. WorldMapMap data transfer requires the use of a PC, a GarminMapSource CD-ROM, and the PC Interface Cable withRS-232 serial port connector supplied with this unit.Follow detailed instructions for data transfer in theMapSource User’s Manual.
