Garmin has several newer models with color and a more sensitive GPS chipset that will work. The Rino 520HCx / 530HCx is my personal favorite. Many of the Colorado, Oregon, and Dakota series will also work. Note that all of these units require a data cable in order to get RS-232 data out of them (Garmin part number 010-10572-00 for the Rino or 010-11131-00 for the Colorado / Oregon / Dakota).<br><br>Any of the GPS / GPSMAP 60, 72, or 76 series with an RS-232 interface will work.<br><br>The GPSMAP 276C is also a popular choice.<br><br>-Jerome, W0JRT<br><br><br></td></tr></table><br>
