View Full Version : old school GPS question

So my father has a 14 year old ( :rofl: ) Garmin GPS 12 XL that finally died on us recently and was looking to move up in the world. But the question is there any way that we can get our GPS numbers from that GPS and move it into a computer then into a more recent GPS without losing game-changing dive spots etc. If anybody has any tips at all please share them!

Thanks, Chas.

If the unit is dead, you are SOL. If it still powers up but is otherwise non-functional, it's possible to hook it to a computer with a serial cable. You'll need the pinouts of a data cable and software such as ocean navigator lite (free from maptech). A db9 connector, a computer with a serial connector (getting harder to find these days). You can go from there.

...and there are serial to USB adapters w/ driver sw at most any computer or office supply store.

Just like any piece of computer equipment that stores data, one day it will fail so you need a backup plan. Most units today allow waypoints to be saved to an SD card, etc. Older units required a PC connection via serial cable as noted in the earlier posts.
If you have a LOT of waypoints you can't afford to lose, backup that data one way or another (even if you need to manually record them all).

Good luck.

If it still powers up then yes can be downloaded, requires a cable and software, something like will work fine.

If that works then that solves your immediate problem and your marks, uploading will be another exercise depending on the new unit.

Even today it makes absolutely difference with regard data management, if you don't regularily backup your system then you must be prepared to loose the data, nothing is fool proof.
