Sonicwall vpn/routing issue!

See attached for my crude site map showing how my sites are connected.

Here is what I got:

1. All sites can talk to the West.
2. West can talk to all other sites.
3. East can talk to South.
4. South can talk to East.
5. North can't talk to East or South.
6. East and South can't talk to North

I'm a bit amateurish when it comes to these static routes and at the time had some free Sonicwall support left over so I had them do everything for me. And the sites that couldn't talk to each other didn't matter at the time. Now we are changing things and they DO need to talk to each other.

Could someone walk me through the steps necessary to set this up? I can send router configs or screenshots if you would like.
