third photo, the hockey puck looking thing with the coax cable attached may be a GPS antenna. You mentioned it has a tracking device in it. Most of them use GPS for the location part, and then a small auto dial cellphone transmitter to send the GPS info with a short data burst to a central alarm center some where. GM's OnStar uses this type of system and it uses Verizon's analog cell phone system nationwide. I'd ask the dealer about it.
Also, the GPS antenna has to sit somewhere that is will have a clear view of the sky. The GPS system (the correct name is the Navstar system, developed by the Air Force) is a constelation of 24 satellites whizzing around the earth in roughly a polar orbit. they aren't stationary like satellite TV or Sirious or XM.
