Labeling a reference graticule in Decimal Degrees

I'm trying to generate a reference graticule for a large-scale map prepared in ArcMap 9.3 which will be used in the field alongside a handheld GPS unit. The field researcher using the this maps prefers to use Decimal Degrees, so I've created a graticule for the data frame with these units(Using the data frame's Coordinate System, WGS_1984_UTM_Zone_36N). While it's possible to define the interval of the graticule lines to Decimal Degrees, it seems impossible to label these lines with the appropriate label in the Decimal Degree units. Is this really true, or have I over looked something?


Mapping Center Answer:

To generate graticule labels in decimal degrees, follow these steps:

  1. Right click the data frame name in the Table of Contents.
  2. Select Properties. Click the Grids tab. Click the New Grid button.
  3. Select the Graticule option. Take all the defaults. Once you are back on the Grids tab, click the Properties button.
  4. On the Labels tab, click the Additional Properties button.
  5. Change the Label Type to Decimal Degrees.
  6. Change the number in Fractional Values to the number of decimal places you will need (this will depend on your map scale).
  7. Click OK to get all the way back to the Grids tab and click Apply to see the changes.
  8. If you want, click Properties again to make any other changes to the graticule and its labels.
