Still not having much joy here.  I've reached the point where I get the 
correct family names properly from the map setup sub-menu, but now 
individual tiles all have the same *area* name, irrespective of what was 
actually set.

Option 1.  (Worst option/broken)
Combine prebuilt gmapsupp.img files into a new, final gmapsupp.img file.

java -Xmx1500m -ea -jar mkgmap.jar --product-id=1 
--mapset-name=UK_merged --gmapsupp
	--family-name="cont_family" --family-id=1402
	./contours/gmapsupp.img CF1402.TYP
	--family-name="base_family" --family-id=1400 	
	./base/gmapsupp.img CF1400.TYP
	--family-name="rout_family"  --family-id=1401
	./routing/gmapsupp.img

Final file size: 283 MB
No OSM copyright message when booting GPS
TYP files are not applied to the layers
Under Menu->Setup map in GPS, all tiles are listed as
, , Dec 2009
*except* two tiles which are listed as
[description], Area 63240xxx, Dec 2009

Under the secondary menu (Menu->Setup Map->Menu) I see
Hide rout_family
Hide
Hide base_family
Hide
Hide cont_family
Hide

Option 2. (Steve's method)
Combine pre-compiled tiles (nb NOT gmapsupp.img files) into a single 
gmapsupp.img.

java -Xmx1500m -ea -jar mkgmap.jar --product-id=1 
--mapset-name=UK_merged --gmapsupp
	--family-name="cont_family" --series-name="cont_series"
	--area-name="cont_area" --family-id=1402 		
	./contours/%contourLayer%*.img CF1402.TYP

	--family-name="base_family" --series-name="base_series"
	--area-name="base_area" --family-id=1400 ./%OSMLayer%*.img 		
	 CF1400.TYP

	--family-name="rout_family" --series-name="rout_series"
	--area-name="rout_area"  --family-id=1401 ./%routingLayer%*.img

Final file size: 284 MB
OSM copyright visible when booting
TYP files are applied to the layers
Under Menu->Setup map in GPS, all tiles are listed as
[description], rout_area, Dec 2009  **Aaargh!!**

Under the secondary menu (Menu->Setup Map->Menu) I see
Hide rout_family
Hide base_family
Hide cont_family **yay - this is what I wanted**

So I've solved the problem of getting the familysets properly visible in 
the secondary map menu, but now individual tiles all share the same 
family name, no matter which family they were originally in.

Yours strugglingly,
