Vintage Garmin GPS 12 12-channel handheld personal navigator with original owner's manual/reference guide.  It is in excellent working condition and will include the 4 AA batteries that it uses.  The internal battery also appears to be working well, it remembered way points after the batteries were taken out for 10 minutes and put back in.  I have since also erased those way points.  Please refer to pictures for additional condition details.  Let me know if you have any questions.
