Tel-Aid System useless, is their another use for the adapter there?

What is your question?

I was not told when I bought this car from carmax of Naperville, IL on 9/03/2010 that the Tel-Aid system, which is a service that controls the cell phone, navi updates, emergency services, etc. was useless because the FCC in 2002 switched from analog to digital which rendered my 2002 AMG Tel-Aid useless. Now I have this cell phone in the armrest that is just a paper weight, but it does have a cord attatched to the system going somewhere. My question is what else can I plug in /attatch (anything would help) to make it useful again? Thank you in advance, james
