Or, if you have PC leads for them both but no software on the PC, I use easyGPS - talks to pretty much anything, and handles waypoints, routes & trails. Not a huge amount of functionality other than copy / paste / edit Waypoints & routes, but for a freebie that works, I'm not complaining.
EasyGPS - Download free GPS software Download the grey clicky box one, not the orannge 14 day trial. (different software). After that it takes about 20 seconds to set up (tell it your GPS type & whether you want to use serial or USB to talk to it) You can also have two or three types of machine saved for a quick swap.
I should also add I am nothig to do with them other than being a happy user.
