![Question](https://mbworld.org/forums/images/icons/icon5.gif)
My telephone company (Verizon) tells me they will no longer provide analog cell phone service after next February. My SL has the hand held Motorla analog telephone that puugs in inside the certer counsel and works through the radio system with a lever on the steering wheel. Has anyone had experience converting this system to a digital cell phone? If so what was the cost and how?
