is there any way to utilize the internal mic built into the 2003 c230k with a different cell phone other than the one that comes with the car? i have a nokia 3360.

 

You can always pop out the cover, and insert the car-kit mike that came with your 'other' carkit in that location. The round black plug with square vented hole above mirror is supposed to be for audio pilot (bose) but I disconnected it and there was no change to the volume changing... so I don't know what it's really for... but that location certainly would hold a standard carkit mike.
