I read somewhere that the Garmin GPS18x pc puck will work with the BCD436. Also does anyone know if the pc to scanner cable that came with the BCD996XT will work as the data cable for the above mentions gps unit. Justt curious trying to use some of the items already on hand, don't want to spend more money if not needed. If the items will work is a gender changer or null modem required. Any and comments will be appreciated.
