The class rating only applies to write speeds. Read speeds are going to be unchanged. Tested on a class 4 16GB in my 1300.

That's my experience with my 1300 too. Whether i run a 1 or 2GB microSD, a 16GB Class 10 microSDHC, or a 4GB/8GB/32GB Class 4 microSDHC the only difference is in the map loading time on start up, read is otherwise the same. Writing data is a different story as stated.

When image files get too large, loading and rendering seem to suffer. I write multiple smaller files to the SD, name them anything you want. Only drawback is you need a computer or smartphone to rename the file you want to gmapsupp.img

While I'm sure writing multiple smaller files and renaming them as you suggest allows you to avoid the segment limit for maps, that sounds like an awful lot of work for little gain. On the flip side, this is sound advice when dealing with older nüvi units such as my 200W. But newer units such as the 1xxx nüvi series as well as some, if not all, 2012 units don't have this limitation if properly prepared. It is possible to have multiple maps running at the same time on these units, as long as those maps have unique filenames and are located in a directory named "Map" on the root of the MicroSD card. Placing the maps in this directory eliminates the need to rename them.
