I have just replaced my 01 X5 3.0 no NAV/ no DSP with a 01 X4 4.4 with NAV and DSP. In my 3.0 I installed the bluetooth kit and the eject box. Everything work very well. The external antenna worked very well. Now I moved everything over to the 4.4 and got the bluetooth working and the eject box. Well the antenna strength on the 4.4 isn't nearly as good as the 3.0. Does anyone know what that could be? I did check the connections and it seems to be connected. The cell strength is better in the cradle but not nearly as good as it was before. I don't know where the external antenna is. Now the 4.4 had a factory cell phone installed before. Could this be the issue?

Thanks,
