I apologize if this is the wrong thread for this question, but without the search function I couldn't seem to locate the correct one. Anyway, Santa just brought me an Explorist600. My CD reader/burner could not read the Mapsend installation CD/DVD. Wasn't there a glitch with blanks CDS sent out? Also, I have Mapsend Topo for the US, that I used for my MeriPlat. Can I use this on the Explorist? Sure hope I don't have to buy a bunch of new software for autorouting and topo.....Finally, thanks to all for the info on the new firmware -- I loaded that before I did anything else, with no trouble.
