Garmin GPSMAP 182C Marine (Untested) Description: Up for sale is a standalone Garmin GPSMAP 182C Color Marine Chartplotter and Fishfinder head unit. Please note: This listing is for the HEAD UNIT ONLY. No power cables, mounting bracket, sun cover, or external GPS antenna are included. This is the perfect, budget-friendly option if you already have the wiring harness, GA 29/30 antenna, and mounting hardware permanently installed on your boat and just need a direct, drop-in replacement display unit. The unit is in good cosmetic shape with standard signs of minor use. The screen lens is clear, and all front panel rubber buttons are intact and tactile. Item is being sold UNTESTED and AS-IS because I do not have the proprietary Garmin power/data cable to boot it up. Display: 5-inch Daylight-Viewab le Color LCD Features: Built-in worldwide marine basemap (coastlines, U.S. tide data)
