I finally got a reply from Garmin - I had emailed and asked them about the new maps........
Good evening,
The 2757 comes with Canada, Mexico and all 50 States pre-loaded.
When you update, it will all go.
One caveatโthe maps grow each quarter. They are so big now that with some units you must use a blank SD/microSD card to hold it all. The 2757 isnโt that way yet.
Garmin Express is the program you need to install a map update:
http://software.garmin.com/en-US/express.html
When itโs done, always verify. Go to the where to/view map page. Tap settings in the lower right. Tap map and vehicle. Tap my installed maps. Make sure it says 2015.20 (thatโs the latest this time). Also be sure it says โallโ with no other languageโjust simply โall.โ That will mean it has Canada, Mexico and all the US.
If when you are done, you would like a double-check please let me know what that page says fully and totally.
Thanks so much.
Best regards,
Loy

So I did the download of both Garmin Express and all the updates - Express pretty much does it automatically. One problem is this is well over 3GB - maybe more - no way I can tell for sure - but it took our Verizon over our monthly allotment so costs us at least $10.
I just look around quickly at a couple of key roads. Yes, the NW loop of the Arco Norte is on there which completes the west coast to east coast cuota. The new devil's backbone between Durango and Mazatlan is also on there. I haven't looked at any more details but if anyone has any specific questions about a specific place I may be able to check. Our 2757LM was very good last year and should be better this year. Only the smallest dirt roads seem to be missing. All updates are FREE with the 2757.
