I realize that there a couple of other threads dealing with MX gps maps but wanted to ask a couple of questions specific to Bicimaps... 1) Do they include info on all of Mex's Pemexs? 2) I read somewhere that bicimaps will erase all other maps on the GPS. Is this correct. Will it wipe all the US maps that came loaded on my Nuvi? 3) How much info is included about hotels, resteraunts and crap like that? 4) ...and now for the subjective question...Is this the best single map-set for a tour of the country that will include most areas of the country? 5) How quickly are the bicimaps atlas delivered. do they come as CD, SD card or are they downloadable. I'm leaving in less than 2 wks, should I just go with garmin's crappy MX map-set to be somewhat sure that it'll arrive in that time. ...opinions and known facts equally appreciated, later.
