I'm strongly suspecting this isn't possible, but I figured I'd ask to make sure. Can you do a backup on a NAM w/2.2 SW and restore partial or all of the backup to a Call Pilot 150?

This is not possible for sure. I specialize in working with both. I know a few people on the "inside" and tell me thats the case.. Sorry Jason

Thanks Jason. Looks like we have some work ahead of us. :-)
