Regarding terminology (Waypoint, Via Point, Shaping Point), notice in your route points list that some are gray and contain "won't alert". Those are Shaping Points. The others are Via Points (alerting). All are referred to as Waypoints. I think the use of "waypoint" when referri...

Strip the outer insulation, unbraided the shielding wires and twist them together to splice and solder to the black lead. A multimeter will confirm that the XT uses the shield as the negative connection. The center wire is the positive, splice to the red lead. Be sure the powered side of the SAE con...

(continuing, hit Submit instead of Preview...) I created the playlists one folder at a time, entering a title for each manually. It might be possible to automate the process in MediaMonkey with a script but after fifteen years with MM, it is beyond my ability. (I can crop a picture in Photoshop, bu...

Unlike the 660 and 59x Garmins, the XT and XT2 cannot act as "mappable" drives. Windows file managers see them as a media device, but they are never assigned a drive letter (C:\, D:\, etc.). That is a problem for most programs. I think you will have many more options if you remove the micr...
