Next project: seeing if I can get TourGuide or Custom POI files to work in the GoldWing. Placed in GoldWing and it booted right up. Dragged my gmapprom file (from backup sd card) over the file and bingo file unlocked. I'm using Win7 and downloaded the zip file. Just follow the instuctions on the provided forum link. The additional maps are not easilly created but if having a larger SD card or having a backup or you have another source for map updates this program works great. Now I can use my new SD card (8gig) with additional maps. I have found a program which will allow me to unlock the detailed map on my copied sd card. I created a copy of the SD card only to find that the detailed map on the copy was locked so I couldn't use it along with my maps (only the basemap which lacks detail). The problem I was having is that I didn't want to create problems with the original sd card supplied with the GoldWing.

I also have a Garmin Zumo 550 and a Nuvi 1300 (no problems here).

I have a 2010 GoldWing w/ nav and am creating my own transparent overlay maps.
