<table cellspacing='0' cellpadding='0' border='0' ><tr><td valign='top' style='font: inherit;'>The 276C, 278, 376C, 378, and 478 should work. If you're also a pilot you may want to look into the x96 family: 296, 396, 496, 495.<br><br>These will all do turn-by-turn routing on roads and generate NMEA. You may need the power/data cable such as Garmin P/N 010-10513-00 or the data only RS-232 cable 010-10514-00.<br><br>-Jerome<br><br>--- On <b>Tue, 7/22/08, Michael J.
