Yep I've since learned that 3.1MB is the disk size limit (Garmin will not be changing this), and resolution limit is 1 Megapixel (@150-155ppi).
Graphic Converter on the Mac has a splitting mechanism that I've been using to divide up my large maps into 4x3 or 3x3, etc. sections. Works well. GC also has a plethora of customizable batch conversion processes that could do splitting and resolution all at once, but I have yet to tackle that. Best part is, GC is only $40 and lets you fully try it, unrestricted, before buying. True Shareware at it's best.
Sorry, I don't know of a PC equivalent.

I love every motorcycle I've owned and even some that I haven't.
