Anyone have any info on the correct procedure for putting in a new base map on the Tmax. I have one in now but want to try a diiferent one. Actually, it is a newer version of the one I am using. I'm not sure if re-initializing is the way to go or if something needs to be done before just rewriting over the old map. I have gone on Zippers site but most of the pages are "under construction". If anyone knows the correct procedure or has any documentation listing the procedure, I would greatly appreciate the info.
