You do not want a SP2620 as it comes with all mapping loaded on a microdrive.
Microdrives are known to fail in high vibration environments (like motorcycles).
The SP2620 does not have a mapping CD that you can load onto your PC (the SP2610 does).
All 3 Garmins mentioned are waterproof to IPX7
Touch screen is easiest to enter addresses
Uses CompactFlash cards which can be bought in large sizes cheaply
No battery for off bike use
GPSmap 276C advantages;
Best screen on the planet
Lots of navigation features
Proprietary memory with max size of 256 MB
If you purchase a SP2610 then price in a 2 GB CF card and bike mount up front
If you purchase a GPSmap 276C then the package is only basic and you should price in City Select mapping, 256 MB memory card and bike mount
I got a 276c, 128mg card Touratech MVG mount (for off road use) City Select all for about $1019 from Cycoactive. I upgraded to the 256 card right away.
Right now I have all of the west Coast From canada to mexico I-5 to the coast, including all of Washington state, in TWO map sets (City Select and Roads and recs) on one 256mg card. That's lots of info!!
I went to the 276c primarily because it seems to be better suited to off-road use, and I can ready the big screen very easily.
Again, call Cycocative. They are really good at helping you select a GPS to suit you.
