07_R & G 320's

I need to have a second cell phone line, and it has to be a Nextel Cell phone. These specific phones operate using a technology called iDEN, which is a Motorola designed cellular protocol used by Nextel. The cell phone itself will run a Java Script, and displays on the little screen of the cell phone dispatch information for a taxi company.

Question is: Are there any phone/puck combinations that will allow me to see what is on the screen of my cell phone? I am not sure if a Razor will yet either...

I have 2 cars, a GL with Navi, and a R without. Both are prewired.

Also - if you cant answer this, can you get me a phone number of a teckie who understands this stuff?

Thanks
