GCScott or anyone that may have an answer,

I and a friend followed your instuctions and all went well. New firmware and 2013.10 map. However, I have a question that you may be able to help me with. I have created transparent overlay maps and installed them on my 2010 Goldwing, a Zumo 550 and a Nuvi 1300 without issues. I used a modified typ file to change the display of the better motorcycling roads. However these maps do not appear on my friends 2008 Goldwing. I noticed the file structure of the CF card only contained gmapsupp.img and associated .unl file and the gupdate.cdg file. We made a backup before starting. Shouldn't there be more .img files? ie: gmapprom, gmapbmap, gmapoem

Due to only having the gmapsupp file to work with, I tried loading my image files from my sd card of the 2010 GoldWing. No luck reading any of the maps. Next we only loaded the 2013.10 map to the cf card gmapsupp.img with positive results. I then combined this map and mine and loaded all using BaseCamp. The 2013.10 map worked but mine were not visible. Tried loading only my maps and nothing appeared. It may have been there but without a basemap we couldn't locate it.

Any ideas or suggestions?
