If it uses the SIM Access Profile (SAP), you're the owner of a 
four-wheeled, combustion engine powered (and therefore in every sense 
mobile) full-fledged phone. The only thing it lacks is a slot into which 
to stick the SIM card (but chances are the circuit board has solder pads 
to connect one :-)).

In that case, usually your hand-held phone will not allow any 
interaction (at least not mobile phone stuff) while connected to the 
car. Also, neither rolling phone nor hand-held will provide any way of 
transferring a call to the respective other.

If you can switch between hand-held and carkit speakers, it's not SAP 
but classic Handsfree Profile (HFP), in which case your phone is still 
doing the hard work and burning battery power.
