1. I have read though both manuals and both quick guides and I'll be ^&*( if I can find the section that details how to program a number in speed dial ) so that I can access my Sprint Voice Command so I can use voice dialing.

2. My car decided to delete the one speed dial that I had programmed. Don't know why.

3. So, please either give me some instructions or a page number for programming speed dialing so I can use it while my car is moving.

 

Start on page 113 in the Navigation owner’s manual which describes how to use speed dial. That page refers you to page 120, which describes how to register up to 17 speed dial numbers.
