I am running a custom 6.5 ROM. Your direction was right on, worked perfectly. I would like to have some waterways maps of my area also. I would like to try: Inland Lakes 2010 v6.00 and Vision g2 VUS515L v11.50. Would these work with the XT 5.00.20w I am running, and could I use the gmapsup2.img and gmapsup3.img directions I have seen on this site?
