I'll start with the usual disclaimer that I searched and couldn't find anything specific to my question.

I'd like to know if, when switching to an aftermarket head unit, do I need to keep the TEL Adapter Unit? (The "white box" that's on the same bracket as the base model stereo)

I looked at the pinout in the FSM in detail, and I could only find a few places where it may be needed:

Telephone integration. Obviously this would be disabled.
Also just as obvious should be that I would not be needing it with an aftermarket headunit
Bluetooth antenna. I would also not use this in an aftermarket head unit
OEM microphone. I will but using the mic that came with the head unit
Steering wheel controls. This one is interesting. I see that the steering wheel controls are routed through the TEL Adapter into the factory stereo. I'm guessing this is only to get the telephone steering wheel controls (but maybe volume as well?). If I get rid of the TEL Adapter unit can I just use the signal that goes INTO the unit from it's connecter without plugging in the unit? I'm guessing yes, but I'm not sure.

Does anyone have any experience with deleting this box? It frees up a lot of space that I'd like to use back there.
