I'm using a RW400 and need suggestions. It came unlocked out of the box running CE5. It has 64 MB RAM and I think a 4.3 inch screen.

I just started a new job where I will be making between 60 to 80 deliveries a day. The only form of nav help they give me is a visual street index, so needless to say I need my GPS up and running again.

I know garmin XT works because I was using it before. I've also used Destinator in the past. Features really don't matter, but route optimization is an absolute must.

So with all that info, which programs are supported by my device that offer route optimization? If there is more than one, which is better in terms of user interface and speed?

Thanks.

iGO primo uses route optimization, I use it with 20 to 25 stops and it works well, although with 64MB of ram you will need to keep the features to a minimum.
