What is best software for adding POIs to my NUVI 660?

[RobertV]

I am looking for some software facility to aid me in finding and adding POIs to my Garmin 660. What are most people using? I found that it was a bear to add POIs to my NAVMAN 550 using their Smart(?) ST software so I would like something that actually works properly.
