ComPilot questions.....

I've ordered the ComPilot and should get it on Friday.

What I would like to know, is can I still have my phone on vibrate and get full advantages on the ComPilot eg the caller identifications?

I can't hear my phone and it drives other people mad being on loud.

I've been told to get warnings only and caller ID. Can you tell me what that means.

If there is anything else I need to know, then please tell me. I have searched but I don't understand the other threads as there is so much to it.
