Input:
I purchased this gps many many years ago and will not repeat what I see many reviewers have said about its usefulness. The one issue I will address has to do with any updates you want to enter into this GPS.  Forget it!  The software they have that is supposed to recognize and upload any firmware update does not work.  It is very old software and looks for COM ports and will not recognize a USB connected Garmin.  This USB connector is something you can buy for use with this Garmin to load updates.  Well, the software didn't keep up with the hardware to load updates and your computer cannot find the Garmin.

Ok, so what you have is a very basic GPS unit.  It will work for simple marking and finding your way back to a certain spot as long as you mark the spots.
