I understand that Minis have a cell antenna built in for iPhone integration. Is it possible to connect a cell phone booster (e.g., something from http://www.repeaterstore.com/applica...-truck-rv.html) to the mini's built-in cell antenna?

 

Don't know the booster question, but the MINI's external antenna is connected into the center armrest. The iPhone does not have an external antenna connection, so they basically set up an inductively coupled antenna in the armrest to bring the external signal into the phone antenna.

They build snap-in adapters for more phones than just iPhones, so you might see if your phone is one of them -- miniusa.com/connectivity is a place to start, I believe.

 

That's a good thought. If possible, I'd like to provide improved signal to all of the phones in the car, though.
