The freezing issue can also be caused by a faulty TCU or a phone that is not compatible with the TCU. The later will give you a SOS error with a phone with a line through it.
I used to get these errors with my iPhone 3GS but every since upgrading to the latest version of iOS 4 (I know there is iOS 5), I haven't had a problem. I just used to reset my iDrive and all was fine. It happens every now and then but much less then before.
You would use the jumper to join the 2 fiber optic cables together to join the loop back up. So behind the HU, or amp, or at the TCU. Basically where ever a module will be splitting the fiber optic cables.
