Rick,
On the newer Garmin eTrex receivers, you can make use of the Trip Computer function to display both latitude/longitude and Maidenhead grid locator. That function also allows a third bit of data to be displayed, and I put the Accuracy figure on there. Then I can take a picture of the GPS display, see my location in two formats, and ensure that the accuracy is within the 20-foot limit as specified in ARRL's VUCC rules. Someone told me about this a few years ago, and I have used that with my eTrex 20 and eTrex 20X receivers since then. You have to set the default position format as "Maidenhead", in order to get that and latitude/longitude on the Trip Computer.
I have a PDF in my Dropbox space http://dropbox.wd9ewk.net/ (look in folder "Garmin_eTrex") that explains how I set this up. I have also sent a copy of this directly to KC7MG, to answer his original question.
73!

One note. I had tried to set up two fields , one with lat-lon the other maidenhead. The trouble they options are for location, so though you can select the fiels twice it will be one or the other format. My solution was to use my back up unit and have one ste for each. Clunky, but it worked.73Rick Tejera (K7TEJ)
