thank you very much for your answer, yes, i'm realizing that i'm about a decade too late to be getting into this "hobby" the way i want, i'm finding a lot of links from 2008 where the whole forum websites no longer exist, never mind the links referenced from specific subject that are now missing.

can i ask one last question, this statement to me seems like it would do the greatest good for me: To make your own transparent road overlay, you could just use openstreetmap data, because then i can load my 24K TOPO map with a latest road overlay and this will give me exactly what i want.

what would be the relevant tutorial to do *explicitly* this task, to just create an .img overlay?

Hi Boyd,

thank you for the quick response.  are you familiar with the GMapTool?   that is what i'm using, i'm also editing properties of the maps right on the sd card inside of the GPS unit.  The tool is telling me the priorities got overwritten to what i wanted them to, but still, pretty much any other map that i have stomps over the 24K TOPO map even though it has priority of 31. 

I wonder if the tool somehow thinks it's writing the data but it's not actually writing that data and GPS doesn't see it?

i wasn't able to find another free tool that manipulated the priority of the maps and this was my quick try at doing that.  is there another tool that could be used?

also, from what you write, it seems like even if i did get it to work it might not work the way i want it to work without me actually getting knees deep into making custom maps?

Hello all,

i've been reading a lot about draw order of maps, i downloaded a free tool that modifies the draw order (1-31) of maps and am still not getting a result that i want and i wonder if it's possible.

-i have some older Garmin TOPO 24K maps that don't have all some of the back roads that show up on Garmin 100K maps that are included with my 66i nor the roads that i'm able to get through garmin.openmaps.nl.

-what i would like to do is enable a "base" map for example something like the 100K or the OpenMaps to show the roads and then on top show the 24K TOPO map so i can have the topo overlay on the roads data.

- i've modified the 24K topo maps to have priority of 30 while all other maps are <20 in priority but anytime i select the 24K TOPO map and any other map, any other map essentially overshadows the 24K TOPO and i can't see it at all underneath the other map.

is there a solution that i can use to force the overlay besides spending another $200 to get the most recent 24K TOPO maps (need 2 regions as i live between two states that unfortunately fall in different regions)?

thanks in advance for your answer.
