Sorry for the basic questions, but I am a total newbie when it comes to
PDA's.


Actually, there's not that much choice in nav software for the Palm. Much
more is available for the PocketPC, which, OTOH, doesn't work well with
your Mac. Personally, I'd go for display size, so you'd want a 480 by 640
resolution. Have a look at Anywhere Map by Controlvision, the "Mercedes"
of PDA nav software. If you want low cost, look at www.pocketfms.com.
