I have a Garmin GPSmap 60CSx that I am trying to keep running and I am looking for an internal part. The part I am looking for is called a PC Holder Garmin Part number 145-00767-00. It is attached to the PC board when you open up the back half of the GPS. The screws which attach the back half screw into it keeping the GPS tightly closed. Link to a photo of the part below. The item in a 60Cx would be identical. Dont know about the earlier 60 series. If someone has old unusable unit for parts I would be interested in purchase. Thanks
