Nuvi 660 and Treo 650 Bluetooth problem

 

I finally paired up my nuvi660 with treo 650. I can receive phone call through nuvi660 but I can't dial out any calls. When I hit the dial button on nuvi660 it does show red icon of phone calling but it doesn't dial. And also i hear nothing through nuvi660. and I don't see my treo 650 light up.
What is wrong?

?

remote sim mode disabled on treo ?
