Inside the car's storage compartment between the two front seats, there's a little jack inside with a lead that comes up to connect to the analog phone.

I'm thinking that maybe I can just buy a lead at the website pops into the little rj-45(??) jack in the storage compartment on one end, and a clip that fits a StarTac/Timeport on the other end, and be good to go.

Has anyone tried this? I don't know squat about wiring and schematics so I don't know if i'm being ridiculous.

Thanks!
