Mtndragon,
Thank you for the feedback. I definitely am more impressed with the quality of the Cartograficas E32 map when compared to the BiCiMapas Mexico GPS Atlas. I guess it is time to get on with ordering a map. By the way, over on the Garmin Mac thread in the "Layin' down tracks" forum, there is a brief discussion of the demise of Road Trip and info on the latest (last week) update to Base Camp for Mac. See this link at pages 106 to 107:
